Description

A method for large-scale seedling cultivation of Niu Dali seeds

technical field

The invention belongs to the technical field of plant cultivation, and in particular relates to a method for large-scale seedling cultivation of Niu Dali seeds.

Background technique

Niu Dali is the root of the beautiful Twig bean genus, which has the effects of relaxing tendons and activating collaterals, clearing away heat and relieving cough, nourishing the lungs and nourishing the kidneys, etc. It is distributed in Guangxi, Guangdong, Hainan, Taiwan, Guizhou and Southeast Asia. edible and medicinal plants. In recent years, due to the continuous increase in sales of various Chinese patent medicines such as Zhuangyao Jianshen Pills and Qiangli Fitness Capsules produced with Niu Dali as the main raw material, the demand for raw materials has also increased sharply. For endangered breeds, the artificial cultivation of cattle has become an inevitable trend. At present, the planting area of Niu Dali is about 30,000 mu. If 600 seedlings are planted per mu, 18 million seedlings are needed. Due to the long flowering and fruiting periods of Niu Dali, the maturity of the seeds harvested in the same batch is inconsistent, resulting in extremely irregular germination of Niu Dali's seeds. Some germinate within a month, and some germinate after half a year, and the germination rate is low. The average is between 42.5-61.25%.

Compared with tissue-cultured seedlings and cutting seedlings of Niu Dali, the seedlings planted and propagated by Niu Dali grow fast, and the diameter of the first year of planting is as large as a finger, that is, the main tuber (potato) is formed, and the seedlings are artificially planted Niu Dali's best choice. However, at present, Niu Dali seeds and seedlings on the market are all carried out on a small scale, coupled with the low germination rate and irregular germination, it is difficult to meet the large-scale demand of the market. Therefore, the present invention has important practical significance to satisfying the market demand for seedlings propagated by cattle vigorously.

Contents of the invention

An object of the present invention is to solve at least the above problems and/or disadvantages and to provide at least the advantages as will be described hereinafter.

Still another object of the present invention is to provide a method for large-scale seedling cultivation of Niu Dali seeds, which can realize the large-scale seedling cultivation of Niu Dali seeds, and hundreds of thousands to several million seedlings can be raised at one time, and the seedlings are neat, and the seed germination rate is between More than 97%, the survival rate is more than 98%, the total success rate of seedling raising is more than 95%, and the seedling raising time can be advanced by 1-2 months.

In order to realize these purposes and other advantages according to the present invention, a kind of large-scale method for growing seedlings of Niu Dali seeds is provided, comprising,

A. Before planting, after finishing the land, reclaim the ground with a width of 1.5 meters when planting, and the distance between the seedlings and the edge of the ground is 30 cm. Plant one tree on each side, and the distance between plants is 80 cm; 300 catties of phosphate fertilizer and 40-60 catties of urea and 40-60 catties of potassium fertilizer are used as base fertilizer; 2) Dig the seedling pit first, add fertilizer to the bottom of the pit and mix with the soil evenly to avoid direct contact between the roots and the fertilizer;

B. Seed planting After the seeds are planted, drench the root water, drench the next day (early or late), insist on drenching two or three times, after planting, do not spray herbicides within five months; drench urea solution after 10 days, use 1-5 Dilute two A urea with 20-40 catties of water, and pay attention to the urea solution not touching the leaves of cattle vigorously; after one month, you can topdress the fertilizer for the first time, and use 60-80 catties of compound fertilizer per mu of land or apply farmyard manure plus urea for topdressing. The amount of manure and urea per mu is 400-600 catties and 40-60 catties respectively;

C. When the support is built for about three months, use wooden strips or bamboo poles to make a strong support for cattle; in the fifth month, you can spray the leaf expander once to control the growth height of the seedlings within 1 meter;

D. Cut the seedlings before and after Qingming. Leave 30cm on the ground, keep two or three seedlings, and cut off the rest. After cutting, the sprouts and leaves will be about 20cm before topdressing. Add urea and potassium fertilizer to the farmyard manure. The amount of farmyard manure per mu is 400 -600 catties, 10-30 catties of urea and 20-40 catties of potash fertilizer or compound fertilizer plus potassium fertilizer, 90-110 catties of compound fertilizer and 50-60 catties of potash fertilizer, after 10 days of top dressing, apply foliar expander; once in June Fertilizer, add 50-60 catties of compound fertilizer and 10-20 catties of potassium fertilizer, and apply it between the two seedlings when topdressing.

Preferably, in the method for large-scale seedling raising of oxalica seeds, when the step A is treated before planting, it can be planted with mulch.

Preferably, in the method for large-scale seedling raising of oxen vigorous seeds, when the seeds are planted in the step B, the distance between the fertilizer and the root of the seedlings is 30 cm.

Preferably, in the method for large-scale seedling raising of Niu Dali seeds, when the seeds are planted in the step B, the foliage fertilizer is sprayed once before the flowering stage in August, and the foliar fertilizer is sprayed once before the fruit stage in October.

Preferably, in the large-scale seedling raising method of Niu Dali seeds, pesticides are sprayed in time when pests are found at ordinary times.

Preferably, in the method for large-scale seedling cultivation of Niu Dali seeds, the Niu Dali seeds are healthy seeds that mature in the same year, have plump granules, uniform size, a purity of over 98%, and are free from pests, shriveled or moldy.

Preferably, the method for large-scale seedling cultivation of Niu Dali seeds also includes multiple times of ultrasonic treatment in the clear water soaking process of the pre-treatment of the seeds, and the ultrasonic treatment conditions are: ultrasonic frequency 200-400Hz, ultrasonic time 20min , The interval between two ultrasounds is 40min.

The present invention at least includes the following beneficial effects:

First, the method provided by the present invention has realized large-scale seedling cultivation of Niu Dali seeds, which can raise hundreds of thousands of seedlings to several million strains at a time, and the seedlings are neat, the germination rate of seeds is more than 97%, and the survival rate is more than 98%. The total success rate of seedling cultivation is above 95%, and the time of seedling cultivation can be advanced by 1-2 months, which solves the problems of irregular germination of Niu Dali seeds, inability to scale breeding and low germination rate;

Second, when planting, use 200 catties of farmyard manure plus 200 catties of phosphate fertilizer and 30 catties of urea and 30 catties of potassium fertilizer as the base fertilizer; mix the base fertilizer with the soil evenly to avoid direct contact between the roots and the fertilizer; make the soil have good air permeability and water absorption, avoid The seeds of Liao Niu Dali are rotten or have low germination rate during the germination process, which improves the germination rate of seeds;

Third, after the seeds are planted, they are planted with mulch, which can maintain a suitable temperature and facilitate germination;

Fourth, the foliar fertilizer can provide comprehensive microelements for the growth of Niu Dali seedlings. The aminohexanoate and brassinolide in the foliar fertilizer can also increase the activity of enzymes in the body of Niu Dali seedlings and increase the chlorophyll in the leaves. content, reduce the transpiration of leaves and promote cell division and elongation, thereby promoting the growth of Niu Dali seedlings;

Fifth, the use of ultrasonic treatment in the process of immersing the seeds of Niu Dali in clear water can stimulate the activity of the enzymes of the seeds of Niu Dali and promote the early germination of the seeds.

Other advantages, objectives and features of the present invention will partly be embodied through the following descriptions, and partly will be understood by those skilled in the art through the research and practice of the present invention.
