Embodiment 1

[0026] 1) Add 1 kg of wood bran, 10 kg of peanut cake, 3 kg of lignite, and 0.005 kg of yeast, after crushing, add about 1.5 kg of diluted urea solution (the weight concentration of urea solution is 10%) for mixing, and mix and stack at room temperature for fermentation Two weeks (or fermented by fermentation equipment, the fermentation time can be shortened to 24-72 hours), after that, dry it in the sun for three days (or dry it with a drying mechanism), and become a dry product of about 10 kg (organic matter ≥ 70%) ), and carry out secondary pulverization, cross 100 mesh sieves.

[0027] Soak 3 kg of attapulgite in 10% hydrochloric acid by weight for 24 hours, dry at 120°C until constant weight, and crush it for later use.

[0028] 2) Add 8 kg of soybean starch with distilled water, gelatinize at 95°C for 30 minutes, cool down to 40°C, add 3 kg of attapulgite, 10 kg of organic matter, 0.3 kg of initiator potassium persulfate, and 20 kg of propylene under vigorous stirring A...

Embodiment 2

[0032] 1) Put 10 grams of wood bran, 150 grams of bean cake, 35 grams of peat, and 0.07 grams of yeast. After crushing, add 20 grams of urea solution with a total concentration of 10% for stirring. After mixing, stack them at room temperature for two weeks (or use fermentation equipment to ferment , the fermentation time can be shortened to 24-48 hours), and then dried in the air for three days (or dried with a drying mechanism), and become a dry product with about 140 grams, which is crushed twice and passed through a 100-mesh sieve.

[0033] Soak 78 grams of attapulgite in hydrochloric acid with a total concentration of 10% for 24 hours, bake at 120° C. to constant weight, and grind it for later use.

[0034] 2) Add 150 grams of soybean starch into distilled water, gelatinize at 95°C for 30 minutes, cool down to 40°C, add 78 grams of attapulgite, 140 grams of organic matter, 6 grams of initiator ammonium sulfate, and 120 grams of acrylamide under vigorous stirring , 2 grams ...

Abstract

A water retention compound fertilizer specially used for soy bean in arid-semiarid regions is formed by mixing water retention agent and compound fertilizer according to the weight ratio of 1-3:8-15; based on the effective content, the composition by weight of the compound fertilizer is that N:P:K:Zn:Mo=1:0.65-1.25:0.95-1.47:0.1-0.25:0.03-0.06; the water retention agent is a mixed type water retention agent and comprises the components of 100-200 parts of organic matter, 0.2-3 parts of active sealing face agent, 150-200 parts of acrylamide, 50-100 parts of starch, 20-50 parts of attapulgite, 20-40 parts of perlite, 2-4 parts of evocating agent and 0.5-1 part of cross linker according to the parts by weight. The water retention compound fertilizer has low cost and convenient application, and can effectively play the role of water retention, fertilizer conservation and long-effect yield growth.

Description

technical field [0001] The invention relates to a special water-retaining compound fertilizer for soybeans in arid and semi-arid areas, which is a water-retaining and drought-resistant compound fertilizer containing various fertilizers, water-retaining agents, coatings and other main components. Background technique [0002] Soybean is a leguminous crop that symbiotically fixes nitrogen. It is not only a grain, feed and oil crop, but also an important raw material for a variety of non-staple food processing. It has a wide range of uses. Most of the N needed in the growth period of soybean depends on the nitrogen fixation mechanism of the symbiotic soybean rhizobia to meet its N supply. Soybean is extremely sensitive to P. After applying P, its yield and quality will be significantly improved. When N, P After the supply is satisfied, K becomes an important limiting factor restricting soybean production. Although the demand for zinc and molybdenum fertilizers during the growt...
