Description

The invention relates to viticulture and can be used for growing seedlings of fruit and wild trees.

The purpose of the invention is to stimulate the process of root formation and lengthen the period of planting seedlings,

Example. In March, in a polyethylene greenhouses create a heat shield of biofuels - bales of plant waste seed alfalfa.

Bales, laid on the base of the greenhouse, are gtolit with water and fertilizers are applied to their surface, which are then washed inside. After warming up and fertilizing the bales, their temperature reaches 40-50 ° C. The planting was carried out after the temperature in the bales of alfalfa was reduced to 30 ° C.

Tanks (polyethylene cups) without bottom are filled with sawdust moistened with liquid mineral fertilizers, and planted in each cup along a cutting or graft to a depth of 15 cm. Cuttings in cups set on bales of plant waste seed alfalfa. After spreading the eyes and forming roots, the dressings are fed with a 0.02% solution of Chssiokov and Bazyrin every other day instead of the last (in the evening. After the roots have been formed, the dressing is done once a week. Root formation, growth and development of seedlings, which occur simultaneously, are more intensively performed.

This is due to the fact that bales from plant waste from seed alfalfa significantly increase the heat capacity of greenhouses. On days with high insolation and lower temperatures, the temperature in lucerne does not change significantly, which determines a more stable course of temperature in the greenhouse due to slower heating of the air during the day and slower thermal output at night.

The greenhouse seedlings are sampled in two terms. The first part of the seedlings

with the onset of good weather, they are planted in 45-50 days, leaving a large area of the PL with the best development of the leaf surface and the root system of the remaining 5 seedlings, which are planted in the fall. On vegetative green saplings, a week before their hardening, they make minting, remove the green growth and leave 2 buds on the seedling. It helps speed up

fO process of forming seedlings (the development of a powerful stem, young shoots), improve the survival of transplanted plants, reduce the evaporation of moisture above the ground part and reduce the cost of subsequent care. Vegetative saplings after

5 embossing vyde (live in the greenhouse 7 -; - 8 days, then planted. Under adverse weather conditions, planting does not produce seedlings. Saplings overgrow somewhat, but do not die.

20 When good weather sets in, vegetative seedlings are planted in open ground.

 “Koria seedlings outgrow the length of stacks and develop in a moist substrate — a heat shield from bales of alfalfa, which serve as a breeding ground. This allows you to lengthen the time of planting the seedlings without reducing their output and to obtain lignified seedlings of good quality with a powerful root system.

The remaining seedlings are grown until October. It does not require five times weeding in greenhouses, loosening the soil and digging out seedlings. In October, woody seedlings with mature growth and undisturbed root system are selected from the greenhouse, and the roots that have penetrated into the rotted alfalfa are easily removed from it. Seedlings are used to eliminate thinning of vineyards or to bookmark new areas. Seedlings planted in a permanent place without damage and renewal of the root system, give a higher survival rate.

Data on the yield of seedlings, depending on the method of cultivation in a polyethylene greenhouse, is presented in Table. one.

Claims (2)

The formula of the invention, the stratification is carried out simultaneously with the cultivation of cuttings and; 1 and pri1. The method of growing wine-vase seedlings, at the same time between the tanks and the basement town of greenhouse conditions, including greenhouses, additionally creates heat stratification, planting cuttings and a graded biofuel screen, wok in the bottomless tank filled with substrate , watering and fertilizer, characterized by 2. The method according to claim I, wherein that, in order to improve the root process, what is used as biofuels is the development and extension of the planting period for seed alfalfa seed.
