example 1

[0062] First weigh each item according to the following weight ratio:

[0063] 60 kg of acrylic acid, 10 kg of sodium hydroxide,

[0064] Potassium Persulfate 1kg, Borax 1kg

[0065] 5 kg of starch, 1 kg of thyrosine,

[0066] 30 kg of conventional fertilizer.

[0067] Then it is prepared according to the following steps: first, the raw materials acrylic acid, starch, thyrosine and borax are polymerized at room temperature, and after 0.5 hours of reaction, the initiator potassium persulfate and the catalyst sodium hydroxide are added, and the second reaction is continued at 70°C. React for 4 hours, discharge, dry and dehydrate, and crush to 0.25mm, then add conventional fertilizers, and pack as a finished product.

example 2

[0069] First weigh each item according to the following weight ratio:

[0070] 80 kg of acrylic acid, 15 kg of sodium hydroxide,

[0071] Potassium persulfate 5 kg, borax 5 kg

[0072] 20 kg of starch, 5 kg of tyrosine,

[0073] 10 kg of regular fertilizer.

[0074] Preparation method is the same as example 1.

example 3

[0076] First weigh each item according to the following weight ratio:

[0077] 70 kg of acrylic acid, 13 kg of sodium hydroxide,

[0078] Potassium Persulfate 2kg, Borax 2kg

[0079] 13 kg of starch, 2 kg of tyrosine,

[0080] 15 kg of conventional fertilizer.

[0081] Preparation method is the same as example 1.

Abstract

The invention discloses a soil water-loss reducer and process for preparation, wherein the water-loss reducer comprises 60-80 weight portions of acrylic acid, 10-15 weight portions of sodium hydroxide, 1-5 weight portions of potassium persulfate, 1-5 weight portions of borax, 5-20 weight portions of starch, 1-5 weight portions of glycocoll, and 10-30 weight portions of conventional fertilizer.

Description

Technical field: [0001] The invention relates to a soil water-retaining agent, and more specifically relates to a soil water-retaining agent and a preparation method thereof. Background technique: [0002] my country's total cultivated land area is 1.5 billion mu, of which the dry land area is 570 million mu, accounting for about 38% of the country's cultivated land area. In addition, there are large areas of barren hills and afforestation areas on dry slopes. Due to the low rainfall and extremely uneven distribution, It directly affects the improvement of agricultural production and the survival rate of afforestation trees; in addition, my country is a country with relatively short water resources. Even the paddy fields that can be irrigated are often suffering from lack of water, resulting in reduced production. The solution to the above problems In addition to actively developing water conservancy construction and water-saving irrigation agriculture, using high-tech product...
