Rice growth resuming medium and preparation method thereof

Abstract

The invention discloses a rice growth resuming medium and a preparation method thereof. The medium is prepared from the following materials: 50-55% of biological organic fertilizer, 35-45% of chemical fertilizer, 3-5% of acid regulating substance and 2-4% of plant growth regulator. According to the invention, high-quality biological organic fertilizer is used as a carrier, quick-acting nutrient elements are reasonably used, and the rice growth resuming medium is used on a seedbed in the later period of seedling growing, so that the seedling growth is promoted rapidly, energy is supplemented, diseases are prevented, new roots are generated explosively, seedling acclimatization is avoided after rice seedlings are transplanted, roots can grow directly, and tillering is started in advance. Therefore, the problem of long seedling acclimatization period is effectively solved, tillering of rice is ensured after transplanting, chemical fertilizers used in the fields and labour are saved, the utilization rate of fertilizers is high, and high and stable yield is realized.

Description

technical field [0001] The invention relates to a high-yield cultivation technique for dry seedling cultivation of rice with sparse planting, in particular to a substrate for rejuvenation of rice and a preparation method thereof. Background technique [0002] Since the promotion and application of rice seedling sparse planting cultivation technology in the 1980s, my country's rice production has taken a leap from direct planting to dry seedling transplanting. The contribution to agricultural production in the past 30 years is huge. The essence of rice seedling sparse planting cultivation technology is: use fertile and loose dry field soil, and in the dry environment of the seedbed, cultivate the seedlings with strong and developed root system, short and thick stems and leaves, and low tillers, and transplant them to the environment with water in the field Medium, fast rooting and greening, in the conditions of long distance between plants, sufficient light, and good ventilat...

AI Technical Summary

Problems solved by technology

Now because we can’t collect the ideal nutrient soil for seedling raising, as long as it is soil, it can be used to raise seedlings by mixing it with seedling strengthening agent , the quality of the seedlings is low, which is a congenital deficiency, the survival rate after transplanting is low, the slow seedling period is long, the rooting is slow, the greening is not turned, and the tillering is delayed

Seedling-strengthening agent manufacturers allow second use of seedling-strengthening agent, fertilizer manufacturers advocate increasing fertilizer application, and pesticide operators recommend spraying more fungicides and regulators. These cannot solve the fundamental problem, increase cost input, and increase useless labor. The effect is not good
