Seedling strengthening nutrition agent special for middle and late rice

Abstract

The invention discloses a seedling strengthening nutrition agent special for middle and late rice, and relates to the technical field of rice planting. The nutrition agent is prepared from, by weight, 40-50 parts of lotus pond sludge, 15-20 parts of mushroom bran, 15-20 parts of sheep manure, 10-15 parts of rice chaff ash, 8-12 parts of grape peel residues, 6-10 parts of ginkgo leaf extract residues, 5-8 parts of rheum officinale extract residues, 5-8 parts of a soil loosening agent, 4-6 parts of croscarmellose sodium, 3-5 parts of gallnut powder, 3-5 parts of magnesium aluminum silicate, 2-3 parts of tea seed powder, 2-3 parts of cane molasses, 1-2 parts of terramycin powder, 1-2 parts of sodium hexametaphosphate, 1-2 parts of sodium chloride, 0.5-1 part of bone black, 0.5-1 part of compound amino acid and 0.3-0.5 part of brassinolide. The nutrition agent has the advantages of being capable of rapidly achieving the fertilizer efficiency and long in fertilizer efficiency, can prevent and control diseases and pests damaging seedlings in a field, reduce adverse influences of the diseases and pests on the seedlings and can solve the soil hardening problem through the soil loosening agent prepared from plant ingredients, food residues and the like.

Description

Technical field: [0001] The invention relates to the technical field of rice planting, in particular to a special seedling strengthening nutrient for middle and late rice. Background technique: [0002] Seedling raising is the first important link in rice cultivation, and it is also the basic work for high yield. It is aimed at cultivating strong seedlings to achieve high seedling rate, uniform seedlings, and strong seedlings, to ensure that enough seedlings are planted in time, and after transplanting, they turn green and survive quickly, tillering early and growing well. The seedling-raising period accounts for 1 / 4-1 / 3 of the entire rice growth period. The quality of the seedlings during the seedling-raising period not only affects the normal differentiation and formation of roots, leaves, tillers and other organs, but also affects the greening, rooting, Tillers and even the number of spikes and grains have far-reaching effects. Seedling strengthening is the key work of ...

AI Technical Summary

Problems solved by technology

Seedling strengthening is the key work of seedling raising. Traditional planting adopts the method of topdressing inorganic fertilizers to strengthen seedlings, which has the characteristics of quick fertilizer effect, but the nutrient element is single, the fertilizer effect is short, and it will have adverse effects on the soil and seriously damage the physical and chemical properties of the soil.
