Method of top dressing of tomato seedlings

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular to crop production. In the method tomato seedlings are grown with water irrigation. To obtain increase in early harvest the tomato seedlings are watered additionally with 0.23% aqueous solution of potassium nitrate KNO3.

EFFECT: method enables to obtain an increase in early harvest by storing the first inflorescences of tomato seedlings.


The invention relates to the preparation of nutrient solutions for growing quality tomato seedlings and may find application in the greenhouse.

Known technology of watering tomato seedlings provide for a centralized system of water supply by hose irrigation or spray irrigation (see "vegetable greenhouse", ed. by Bryzgalov, V. A., Sovetkinae V. E., Savinova N. And. 1995, 352 p.).

Are the irrigation methods do not provide a uniform feed of the root system of tomato. During irrigation, the nutrient reserves in the soil are washed away by water, the plants do not get sufficient nutrients for the formation of the first blossoms. The seedlings in these glazes are formed high juicy stems with loose tissues, due to the large amount of free water in Miletich spaces. When transporting seedlings in the greenhouse for planting plants susceptible to breakage of the stem and the fall of the first inflorescences, resulting in lower early yield of tomatoes.

The aim of the proposed method of watering tomato seedlings is to choose the necessary nutrient elements in solution and applying these solutions to the root system in the seedling period of plants.

This object is achieved in that during the growth of tomato seedlings used different nutritional� solutions to determine more efficient. For the preparation of nutrient solutions with a concentration of 0.23% of the applied fertilizer:

1st solution - KNO3potassium nitrate.

2nd solution - KNO3+CA(NO3)2potassium nitrate and calcium nitrate.

3rd solution - NH4NO3+K2SO4ammonium nitrate and potassium sulfate.

Control option - watering of seedlings with water.

The experiments that were conducted to determine the quality of seedlings when grown using each of the proposed solutions separately, allowed to compare the development of tomato plants compared with irrigation water without fertilizer. When watering, the inventors of solutions in the soil increases the total salt content of nutrients.

Fertilizing tomato plants with solutions containing KNO3+Ca(NO3)2- potassium nitrate+calcium nitrate and NH4NO3+K2SO4- ammonium nitrate+potassium sulfate, contributed to the growth of the vegetative mass, but delayed the development of the inflorescence.

Seedlings grown on the proposed technology with the use of the nutrient solution KNO3- potassium nitrate, was developed more - the volume of the root system the first two inflorescences of plants of tomato were on 1X organogenesis stages, promotes the formation of early harvest 1.5 kg/m2higher in comparison with the harvest collected from the area who poured water over it.

Watering tomato seedlings grown with irrigation water, characterized in that to obtain a raise early harvest tomato seedlings additionally watered 0,23% aqueous solution of potassium nitrate, KNO3.
