Problems solved by technology

[0002] my country is a large agricultural country, and the output and usage of chemical fertilizers rank among the top in the world. However, in agricultural production, the seasonal utilization rate of various chemical fertilizers is low, and is lower than the level of developed countries in the world. According to statistics, the fertilizer utilization rate is about: nitrogen fertilizer 20%-35%, phosphate fertilizer 10%-25%, potassium fertilizer 35%-50%, the reason is that excessive fertilization and improper methods have caused a large w

Example Embodiment

[0023] Example 1

[0024] The formula (mass percentage) is: polyacrylamide 40%, lignin 25%, sodium dodecylbenzene sulfonate 10%, and additives 25%. The additives include the following components in terms of mass percentage: inorganic salts (phosphate 10%, carbonate 5%, silicate 5%) and organic additives (carboxymethyl cellulose 3%, sodium toluenesulfonate 1% ), anti-caking agent 1%.

[0025] The preparation steps are image 3 Shown

[0026] The sample was in the form of white powder, and the pH of its solution (diluted 200 times) was measured to be 6.5-7.0.

Example Embodiment

[0027] Example 2: Effect of sample on soil porosity and field water holding capacity

[0028] 2.1, the purpose of the experiment

[0029] By measuring the changes in soil porosity and soil field water holding capacity before and after use, the change in soil porosity reflects the improvement effect of the sample on the soil structure, and the field water holding capacity reflects the size of the soil water holding capacity and reflects the improvement of the sample’s soil moisture effect.

[0030] 2.2. Test materials

[0031] Ring knife soil extractor, balance, pycnometer, heating mantle, oven, filter paper, petri dish, porcelain plate, etc.

[0032] 2.3. Test method

[0033] Choose a piece of 100m 2 The soil was tested and divided into two equal parts, one was irrigated with a sample (200g per mu, first dissolved in 200-400kg of water, and then flushed with water), and the other was irrigated with water. One week later, soil was used for experiment in both the treatment field and the ...

Example Embodiment

[0047] Example 3: Effect of the sample on the growth of wheat seedlings after improving the soil

[0048] 3.1 Test purpose

[0049] Through indoor testing, the influence of the sample on the growth of wheat seedlings after improving the soil provides a reference for field experiments.

[0050] 3.2 Test conditions

[0051] Room temperature (20°C).

[0052] 3.3 Test procedure

[0053] Control (CK): Put 500g of soil in a 500ml beaker, sow 8 wheat grains in each beaker, pour clear water until the soil is moistened;

[0054] Treatment (sample): Put 500g soil and 1g sample into a 500ml beaker, mix them evenly, sow 8 wheat grains in each beaker, and pour clean water until the soil is moistened;

[0055] Each treatment was repeated in 20 groups. After germination, the soil was kept moist and cultured for 8 days. Five plants were randomly selected from each group to investigate the shoot length, root length and root number. The results are as follows figure 2 , Table 2 shows.

Abstract

The present invention relates to a soil loosening activator and an application thereof. The soil loosening activator composition comprises polyacrylamide, lignin, sodium dodecylbenzenesulfonate and anassistant, and a mass ratio of the polyacrylamide to the lignin to the sodium dodecylbenzenesulfonate is (50-10):(45-10):(25-10). The soil loosening activator of the invention can adjust and improvethe aggregate structure of soil, slow down the hardening of soil, enhance the water and fertilizer permeability in the soil, improve the water retention rate, promote the growth and development of beneficial microorganisms in the soil and the growth and development of crop roots, enhance the disease resistance and significantly increase the yield.

Description

technical field [0001] The invention relates to the fields of chemical industry and agriculture, in particular to a soil loosening activator and its application. Background technique [0002] my country is a large agricultural country, and the output and usage of chemical fertilizers rank among the top in the world. However, in agricultural production, the seasonal utilization rate of various chemical fertilizers is low, and is lower than the level of developed countries in the world. According to statistics, the fertilizer utilization rate is about: nitrogen fertilizer 20%-35%, 10%-25% of phosphate fertilizer, and 35%-50% of potassium fertilizer. The reason is that excessive fertilization and improper methods have caused a large waste of resources and environmental pollution. Among them, the leaching loss of fertilizer nutrients in the soil is an important reason for the low nutrient utilization efficiency. The loss of fertilizer nutrients not only increases the cost of agri...
