Description

Integrated production method of nutrient liquid film hydroponics for root leek

technical field

The invention relates to the field of vegetable cultivation, in particular to a method for the integrated production of nutrient liquid film hydroponics for root leek.

Background technique

Root leek (Allium hookeri), referred to as root leek, also known as leek, broad-leaf leek, is a leek variety that mainly produces fleshy roots. The fleshy root of leek is slightly less spicy than the leaves. It is a common vegetable in some areas of Yunnan and Guizhou. Its taste is spicy and tender. It can be cold, pickled and fried, and is very popular among the public. The root system of leek is rich in cellulose, carotene, vitamin C, and volatile thiopropene, etc. It has a spicy taste, can increase appetite, and also has the functions of dispersing blood stasis, promoting blood circulation, and detoxification. The succulent roots of chives can also be made into pickled products, and the market response is excellent and the demand is large.

At present, leeks for root use are mainly cultivated in the field, which requires a lot of manual excavation of fleshy roots during the harvest period, and the labor cost is very high. In addition, the root system of leek for root is huge, randomly distributed around in the soil, the length can reach 20-30cm, the roots are intertwined, and the fleshy roots are brittle and tender, which are easily broken. In the clay planting area, the yield loss caused by the excavation process can reach 20%. %～40%. In the soil cultivation environment, the roots of root leek are also susceptible to root rot, cotton rot, leek maggots and nematodes and other diseases and insect pests, which have a serious impact on the yield and quality of root leek. Due to the large number of damages in the artificially excavated root leek, it is very easy to cause serious economic losses due to rot and mildew caused by wound infection during storage and transportation.

The application of hydroponics technology can well solve many problems in soil cultivation. Compared with soil cultivation, hydroponic root leek cultivation has obvious advantages. First, the growth space of hydroponics roots can be adjusted according to the degree of plant root development, which can ensure sufficient growth space for roots; secondly, hydroponics can effectively control the harm of soil-borne diseases and leek maggots, reduce the application of chemical pesticides, and meet the requirements of safe and green production. requirements; third, root growth without mechanical resistance, strong and upright, white in color, and excellent commerciality; fourth, harvesting is very convenient, without manual digging and cleaning, which can greatly reduce labor costs; the most important thing is that water bacon and leek are harvested. It can avoid mechanical damage to the root system, facilitate storage and transportation, and reduce the loss caused by root leek storage diseases. Hydroponics can also control the nutrient solution more precisely to regulate the growth of root leeks above and below ground.

Hydroponics has been widely used in leek cultivation, especially the hydroponic production technology of leafy leek is relatively mature. Leaf leek has a thin fleshy root system and does not require much space for growth. As long as a good supply of nutrient solution and gas exchange to the root system can be ensured, a higher yield of leafy vegetables can be obtained. The root system of root leek is very large. If the conventional leaf leek production device is used for cultivation, it will easily cause root growth restriction and hypoxia and root rot. Therefore, it is urgent to develop a hydroponic device suitable for root leek and supporting cultivation management measures to accelerate the vegetative growth and root yield formation at the seedling stage, so as to achieve safe, stable, green and efficient hydroponic root leek production.

The composition of the nutrient solution can regulate the growth of the above-ground part and the underground of the plant, among which the phosphorus element has the most obvious effect on the regulation of the root system. When plants are deficient in phosphorus, they generally show small leaves, reduced branches and tillers, dwarf plants, and developed root systems, such as increased root length and root-shoot ratio, and more lateral roots and root hairs. Therefore, in order to control the leggy growth of the aerial part and coordinate the growth of the fleshy roots in the underground part, the phosphorus content must be controlled. However, under low phosphorus, the root system became thinner, and the small lateral roots of the fleshy roots increased, resulting in a decrease in edible quality. Excessive nitrogen in the nutrient solution can promote the leggy growth of shoots and leaves in the aerial part, reduce the ratio of root to shoot, and is not conducive to the growth of plant roots and the downward transport of photosynthetic products. High nitrogen nutrient solutions also lead to decreased plant disease resistance and increased risk of root disease. Therefore, in the hydroponic production of root chives, the yield and quality of fleshy roots are affected by the formula of the nutrient solution.

SUMMARY OF THE INVENTION

The practical nutrient solution formula in the above-mentioned hydroponic process is shown in Table 1.

Table 1, the nutrient solution formula of root leek seedling growth stage and hydroponic production stage

Table 1 (continued)

(2) Nutrient solution management technology

During the hydroponics process, the nutrient solution was replaced every 20 days, the temperature was 25±2°C, and the pH value was 6.2±0.2; the first 20 days of seedling stage: the planting plate was directly floated on the nutrient solution, the depth of the nutrient solution was 3-5cm, and the circulation time was 3min , with an interval of 20min; tillering stage: the planting board is raised by 5cm, the nutrient solution depth is 3cm, the circulation time is 3min, and the interval is 20min; the prosperous stage: the planting board is raised by 10cm, the nutrient solution depth is 2cm, the circulation time is 2min, and the interval is 10min; Stage: The planting plate is raised by 12-15cm, the depth of the nutrient solution is 1-2cm, the circulation time is 1min, and the interval is 10min.

(3) Root leek vegetative growth period management

A. Remove buds in time to prevent plant aging;

B. Depending on the growth of the root system, gradually raise the planting board and reduce the depth of the nutrient solution to reduce the time between the root system and the nutrient solution and prevent the root system from hypoxia and necrosis.

C. Remove the senescent yellow leaves at the base to prevent pollution and pipe blockage caused by falling into the nutrient solution.

D. Harvest in time before the full bloom period to prevent root trees

(4) Harvesting of succulent roots of root leek

When the fleshy root of the root leek grows and expands to the maximum length of 30cm per hole and the weight is about 100, it can be harvested. When harvesting, first use scissors to cut off some leaves on the ground, and then gently pull down by hand, the root leek is separated from the planting board. Remove the excess leaf sheaths on the upper part and the senescent rotten roots on the lower part.

(5) Post-harvest treatment of root leek

Hydroponic leek has high water content and low degree of lignification. If the post-harvest treatment is improper, it will easily lead to root rot and post-harvest loss.

A. Rinse with clean water: The harvested leek root should be rinsed with clean water in time after the rotten roots and the excess leaf sheaths on the upper part have been removed, and it should be as gentle as possible to avoid damage.

B. Put the leek root in a bamboo dustpan and spread it into a thin layer, put it in a dark, ventilated and dry place at 20 ~ 25 ℃ to dry the surface moisture, and make the leek root wilt and soften, so as to promote the surface contraction of the fleshy root and increase its resistance to pathogenic bacteria. resistance. In the meantime, reduce the time the roots are exposed to light to prevent them from turning green.

Using the method of the present invention to detect the growth effect of root leek, taking the soil cultivation in small pots under the same period and the same climatic conditions as a control, the results are shown in Table 3.

Table 3, the comparison of plant growth effect between hydroponic production of root leek and traditional soil cultivation (planting for 50 days)

Note: lowercase letters indicate significant difference at p≤0.05 level.

It can be seen from Table 3 that compared with traditional soil cultivation, the plant height and stem diameter of hydroponic root leek increased significantly, but the number of tillers decreased significantly. There was no significant difference in root vigor between the two cultivation methods.

Then, the hydroponics method and the yield of succulent roots of soil cultivated plants were counted, and the results are shown in Table 4.

Table 4, the comparison of succulent root output of root leek hydroponic production and traditional soil cultivation plants (planting 70 days)

It can be seen from Table 4 that compared with the traditional soil cultivation, the quality of the aboveground part and the underground part of the succulent root were significantly improved, and the root length also increased to a certain extent, but the increase was not obvious.

The biggest difference between the two cultivation methods is also in the quality and efficiency of harvesting the succulent roots. The root leek cultivated in soil is troublesome to harvest, and the tender root system is easily broken in the soil, causing a lot of losses; and the excavated root system contains a lot of soil, and it needs to be soaked and washed with a lot of water, which is time-consuming and labor-intensive.

Under the nutrient liquid film cultivation, the yield is significantly higher than that of the soil cultivation. The most important thing is that the root system is intact and tender, the harvesting and cleaning are convenient, the efficiency is high, and the root loss is low, which can realize the factory production of root leek. However, the water content is high and the root system is low in mechanization. If it is not handled properly after harvesting, it will easily cause rot. The treatment method introduced in the invention can significantly reduce the incidence of root rot and prolong the storage time of fleshy roots. In addition, fibrous fibrous roots are easy to grow on the fleshy roots in root leek hydroponics, which will have a certain impact on the edible quality of the root system. This will be a technical problem that we will focus on in the next step.

The above-mentioned embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention. The protection scope of the present invention is subject to the claims.
