Embodiment 1

[0020] In 2015, this product was used in combination with drought-resistant varieties and water-saving irrigation in the high-yield creation technology demonstration of the Tongxu water-saving agricultural base in the Henan Super Grain Province Award Fund Project "Wheat-Corn Water-Saving, Fertilizer-Saving and Efficiency-Enhancing Technology Promotion and Application" project Combined with its water and fertilizer integration technology, the wheat yield can be increased by more than 10%.

Embodiment 2

[0022] In 2011, the experiment on the effect of combined application of nitrogen and phosphorus on sandy fluvo-aquic soil in Dongxinzhuang Village, Xuncheng Township, Yanjin County showed that the effect of 0-90kg / hm 2 Within the dosage range, at the N90P90 fertilization level, the yield increased with the increase of the soil conditioner, and the yield increased from 10.74% to 14.71%; at the N90P135 fertilization level, the conditioner was 60kg / hm 2 It reached the best level with an increase rate of 15.00%; at the application level of N180P90, with the increase of the amount of soil conditioner, the range of increase in peanut yield decreased; at the level of N180P135, the range of increase in peanut yield first decreased and then increased The process, that is conditioner 90kg / hm 2 It reached the best level at , with an increase of 18.97%. At the same time, the organic matter content of the soil plow layer increased by 0.10-0.24g / kg compared with CK, the available phosphoru...

Abstract

The invention discloses a soil conditioner comprising, by mass, 20-25% of polyacrylamide, 15-35% of organic matter, 10-25% of humic acid, 12-23% of amino acid, 18-35% of nitrogen phosphorus and potassium. The soil conditioner has the functions of increasing soil active substances, improving soil structure, improving soil capacity and storage capacity, reducing soil ineffective evaporation, and isharmless to crops, environment, people and livestock.

Description

technical field [0001] The invention belongs to the technical field of soil improvement products, and relates to a soil conditioner, more specifically, to a novel organic nutritional soil improver for soil water retention, soil improvement and soil nutrition. Background technique [0002] The effect of soil improvement agent on soil improvement is very obvious, and it has many functions, but there are still some main problems as follows: 1. The cost is high. Although there are many development units, they dare not produce on a large scale, resulting in high cost and high cost, so that they cannot be obtained. ②Insufficient technical training and poor promotion. Soil conditioner is a new type of product. Many farmers do not understand it, let alone how to use it. The technical development department and the competent agricultural department did not communicate and cooperate in time for training and promotion. The use of soil amendments is limited; ③There are many types of soi...
