Abstract

FIELD: agriculture.

SUBSTANCE: method includes mulch planting of grafters and getting rosettes. Row-spacings being filled with rosettes, they are mulched with 3-4 cm layer of substrate, grown, left on mulch film until root system develops; thereafter they are separated from the grafters.

EFFECT: cost reduction and reduced labor intensity of growing.

Description

The invention relates to agriculture, in particular to horticulture and can be used in the cultivation of strawberry seedlings.

A known method of producing seedlings of strawberries directly from the uterine plant. However, rooting rosettes in a uterine plant makes it difficult to control weeds, which takes up more than 25% of all labor costs (Chukhlyaev I.I., 1984), only 50% of rosettes develops in standard seedlings (Efimenko D.I., 1988), on heavy it is difficult to obtain a sufficient amount of standard seedlings in soils (Shatalova MA, 1975), digging seedlings is a very laborious process (Polikarpova F.Ya., 1987).

There is also known a method of growing strawberry seedlings using mulching material (film), followed by picking outlets (Efimenko D.I., 1988, Chukhlyaev I.I., 1984). However, it requires a lot of manual labor and the creation of additional ridges for a dive.

The objective of the present invention to exclude weed control, picking, from the cultivation technology of strawberry seedlings, to reduce the need for cultivation area, to facilitate harvesting of seedlings, to improve its quality.

This is achieved by growing strawberry seedlings using double mulching. The mother plants of wild strawberries were planted on a mulch film. After filling the aisles with the obtained sockets, they are additionally mulched, falling asleep with a layer of 3-4 cm, after the development of the root system on the sockets, they are simultaneously separated from the uterine plant.

The use of mulching significantly increased the yield of strawberry seedlings. The degree of increase depended on the type of second mulching. The maximum increase was observed in the peat variant. The use of various materials as the second mulching layer influenced the growth and development of strawberry seedlings (Table 2).

Growing rosettes along the mulch film stimulates the laying of rudimentary roots in them, the length of which before applying the second mulching layer does not exceed 0.5-2 cm. After applying the second layer to them, the roots begin to grow and branch intensively. The root system developed better when using peat, which is associated with its increased moisture capacity. The lack of nutrients in the sand, as well as its high duty cycle and specific gravity negatively affected the development of the root system of seedlings. Growing strawberry seedlings using a peat layer changed the nature of its harvesting, digging was much easier, for which it was necessary to cut off the burial coming from the mother plant with a knife, and at the same time to separate all the seedlings that developed from the mother plant. Seedlings grown with double mulching and left in the mother plant were not damaged in winter. All plants were alive and met the requirements of the standard. The entourage, connecting the sockets among themselves, perished during the winter, which made it easier to clean the seedlings in the spring.

Claims (1)

A method of growing strawberry seedlings, including planting uterine plants on a mulch film and obtaining rosettes, characterized in that after filling the row-spacings with the obtained rosettes, they are mulched, falling asleep with a layer of 3-4 cm, and then grown, leaving on the mulch film until the root system develops, after which the resulting seedlings are separated from the mother plant.
