Anti-bacterial nutrient solution for seedling tray nursing medium

Abstract

The invention discloses an anti-bacterial nutrient solution for a seedling tray nursing medium.The anti-bacterial nutrient solution is prepared from, by weight, 50 g of rose hydrosol, 10 g of isolated soybean protein, 100 g of ADK emulsion, 15 g of sodium acetate, 2 g of magnesium sulfate, 2 g of magnesium phosphate, 50 g of brassin, 50 g of modified wheat flour, 30 g of fruit wine, 15 g of semen brassicae powder, 10 g of radix notoginseng powder, 10 g of cortex dictamni powder, 15 g of compound sodium nitrophenolate, 10 g of milk powder and 800 g of water.The anti-bacterial nutrient solution is prepared by mixing the ingredients to be uniform in the water; when the anti-bacterial nutrient solution is used, every square meter of seedling nursing trays are sprayed with 150-200 ml of the anti-bacterial nutrient solution, nutrients can be supplied to seedling growth, generation of disease and pest damage is reduced, and healthy and strong growth of seedlings are guaranteed.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a germ-preventing nutrient solution for seedling-raising substrates in seedling trays. Background technique [0002] Since the 1980s, rice dry-raised sparse planting cultivation technology has been widely used in my country through introduction, experimentation and demonstration. With the great leap forward, rice production has developed rapidly, presenting a gratifying situation today, with large planting area, high per unit yield level, the total output ranks first in grain output, and remarkable economic benefits. [0003] The essence of dry rice seedling sparse planting and transplanting technology is: use fertile and loose dry field soil, and in the dry environment of the seedbed, cultivate strong and developed root system, short and thick stems and leaves, and low tiller seedlings, and transplant them to paddy fields After the environment, it will burst into roots and...

AI Technical Summary

Problems solved by technology

When the drought seedlings were first raised in the countryside, the farming was done according to the technical requirements. The seedlings cultivated were of good quality, turned green quickly, had many tillers, high yields, and were disease-free and disaster-free. Farmers have personally experienced this. It is very difficult to handle topsoil, decomposed farmyard manure and peat. There are few livestock and poultry, and low-lying floodplains, meadows, and grass ponds where peat can be dug have all developed into paddy fields. Most of the dry fields with water sources They have also been converted into paddy fields. Each hectare of seedlings requires 2m3 seedling soil per year. After years of continuous excavation, all the dikes and wasteland resources in the paddy field area have been exhausted. Knowing that the current seedling soil is far from the dry farming technology The purpose, there is really no way, now seedlings are raised regardless of black soil or loess, beside the roadbed, under the ditch, as long as it is dry and can be sieved into fine soil, it can be used as seedling bed soil. The seedling soil is barren, hardened, and cold , the seedlings bred are slender and have few roots, excessive growth and disease, low survival rate after transplanting, slow turning green, late tillering
