Problems solved by technology

However, due to the strengthening of farmers' awareness of the use of chemical fertilizers, especially the characteristics of convenient use and quick results, chemical fertilizers have been widely used in soybean crops, resulting in soil compaction, which has become one of the main factors affecting the decline in soybean yield.
[0004] In addition, due to the limited arable land area in our country, which is mainly used for rice, wheat, soybean and other crops, it is difficult to increase the yield of soybean rapidly, the total yield is seriously insufficient, and the per unit yield is low

preparation example Construction

[0029] The preparation steps of control group 1, control group 2 and control group 3 are the same as in Example 3, wherein control group 1 does not add acetylcholinesterase, control group 2 does not add soybean plant extract, and control group 3 does not add alkaloids.

[0030]

[0031] The preparation method of the soybean plant extract in Examples 1 to 5 of the present invention and the control group 1 comprises the following steps:

[0032] (1) collection of soybean plants: after the soybeans are harvested, the soybean plants are collected;

[0033] (2) Pretreatment: the soybean plants collected above are rinsed with clear water and dried, and the collected plants are divided into stems and roots after drying;

[0034] (3) Plant extract: the stem and root are respectively subjected to a stem extraction process and a root extraction process, and a stem extract and a root extract are obtained accordingly.

[0035] Wherein: described stem extraction process comprises the f...

Abstract

The invention discloses a high-efficiency slow-release fertilizer for soybeans. The fertilizer is prepared from, by weight, 3-6 parts of acetylcholinesterase, 2-5 parts of alkaloid, 10-16 parts of soybean plant extract, 4-6 parts of rhizobium inoculant, 4-6 parts of bacillus subtilis, 3-7 parts of urease, 3-6 parts of o-phenylphosphoryl diamine, 35-45 parts of urea, 35-45 parts of monoammonium phosphate, 30-45 parts of potassium chloride, 15-22 parts of calcium superphosphate, 5-15 parts of magnesium sulfate, 0.1-1 part of manganese sulfate, 0.1-1 part of copper sulfate, 5-15 parts of borax, 10-15 parts of ferrous sulfate and 5-10 parts of binder. The soybean plant extract is composed of a stem extract and a root extract, and the weight ratio of the stem extract to the root extract is 5:1-8:1.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a high-efficiency slow-release fertilizer for soybeans. Background technique [0002] The scientific name of soybean is soybean, which is a leguminous plant with an oval and spherical shape. Mainly produced in Northeast China, it is a crop whose seeds are rich in protein. It is most commonly used to make various soybean products, extract soybean oil, brew soy sauce and extract protein. Soybean is the fourth largest grain crop in my country and is also used as an oil plant. It is the main source of plant protein nutrition and high-quality oil nutrition for Chinese people; soybean meal is an indispensable source of protein feed for aquaculture. Soybean is an important crop in ecological agriculture and organic agriculture due to the nitrogen fixation effect of root nodules. So soybean cultivation plays a vital role. [0003] Soybean has the rhizobia of leguminous crops, which can fix ...
