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, and it takes 2m per hectare to grow seedlings per year 3 Seedling soil has been excavated for many years. All the dikes in the paddy field area and the resources of wasteland have been exhausted. Knowing that the current seedling soil is far from the purpose of dry breeding technology, there is really no way. The loess, beside the roadbed, and under the ditch, as long as it is dry and can be sieved into fine soil, it can be used as seedling bed soil. If it is not fertile, it will be supplemented with chemical fertilizers. The roots are long and diseased, the survival rate is low after transplanting, the greening is slow, and the tillering is late. It is not at all to achieve high and stable yields with high-quality seedlings, but to press the yield on chemical fertilizers and weather. When the year is good, the yield can be maintained, and there is a slight disaster. Rice farmers are miserable. If there is a spring flood year, there will be water everywhere and nowhere to collect soil, and there will be no way to do anything about agricultural production, which will delay the farming time.
[0005] At present, many units are studying the technology of rice seedling cultivation without soil, and they mostly use mineral materials such as expanded particles, fine sand or perlite as fillers, combined with inorganic fertilizer nutrients, practical application, and the practical effect of agronomy is very unsatisfactory.

Abstract

The invention relates to seedbed soil for the dry-seeding and sparsely-transplanting seedling cultivation of a rice seedbed. The seedbed soil is prepared from the following components in parts by weight: 1000 parts of farmyard manure, 50 parts of modified rape pod shells, 10 parts of calcium superphosphate, 10 parts of potassium chloride, 300 parts of loess, 30 parts of sepiolite powder, 20 parts of nanometer silicon dioxide, 50 parts of sea mud, 50 parts of sepiolite fabrics, 10 parts of sodium selenite, 5 parts of tea alkaloid, 20 parts of seaweed micropowder, 60 parts of urea, 20 parts of modified corn starch, 15 parts of chelating zinc, 50 parts of calcined kaolin, 50 parts of rape seed cakes, 20 parts of shell powder, 50 parts of bagasse and 20 parts of soil fungicide. The matrix of the seedbed soil disclosed by the invention contains organic matters more than 40%, humic acid more than 20% and beneficial microorganism living strain of 6000 myriad per milliliter. A seedling raised by applying the seedbed soil disclosed by the invention has the advantages of multiple seedling root system, multiple root hair, large root volume and no seedling stage disease generation, is returned to green and unnecessary to recover after being transplanted, directly roots to be survived, starts the effective tillering in advance and can realize the output increase and the income increase.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a bed soil for dry and sparse planting of rice fertilizer beds. 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 turn green quickly.
