Multiple-effect nutrient for rice upland seedlings

Abstract

The invention relates to a multiple-effect nutrient for rice upland seedling. The multiple-effect nutrient comprises the following components by weight percent: 0.80-1.20% of trichoderma harzianum or trichoderma, 0.80-1.20% of paenibacillus polymyxa, 0.80-1.20% of bacillus thuringiensis, 32.50-53.75% of ammonium sulfate, 9.09-15.91% of ammonium dihydrogen phosphate, 0.63-1.25% of potassium chloride, 5.25-10.50% of potassium sulfate, 1.50-3.00% of zinc sulfate, 1.00-2.00% of ferrous sulfate, 0.6-1.0% of manganese sulfate, 0.02-0.06% of abscisic acid (ABA) (Acid exists in Abscisic), 0.1-0.4% of15%(wt) Paclobutrazol and 22-34.08% of filler, wherein the filler is bentonite or grass carbon. By using the multiple-effect nutrient, a four-in-one rice upland seedling requirement can be achieved, i.e., soil acid adjustment is achieved, disease, insect and stress resistances are achieved, the nutrition demand is met, the growth is regulated and tillering is promoted, thereby being beneficial tocultivation of multiple-tillering seedling and achievement of high yield and increment of rice.

Description

technical field [0001] The invention relates to an agricultural composition, in particular to a multi-effect nutrient for rice seedling raising in dry land. Background technique [0002] Compared with paddy rice seedling raising, rice seedling raising in dry land is different. The production of rice seedlings in dry land usually requires acid adjustment, pest control, nutrition, chemical control, etc. At the same time, rice seedlings are susceptible to various diseases and insect pests such as blight, damping-off, cotton rot, root rot, cutworms, needleworms, mole crickets, earthworms, scarabs, etc. , Dead seedlings occur. Under dry land conditions, due to different growth environments, it is more likely to cause symptoms such as nutrient imbalance, yellow seedlings, weak seedlings, and lack of nutrients. At the same time, in the early stage of seedling cultivation, the temperature is unstable, and the low temperature and cold wave cause the seedlings to suffer from cold d...
