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 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 rate. The loss of fertilizer nutrients not only increases the cost of agricultural input, but also causes serious pollution to the environment, especially water resources.
[0003] On the other hand, the quality of cultivated land in our country has declined sharply, and soil problems have become increasingly serious due to long-term unreasonable fertilization and planting habits.

Embodiment 1

[0024] The formula (mass percentage) is: 40% of polyacrylamide, 25% of lignin, 10% of sodium dodecylbenzenesulfonate, and 25% of additives. Wherein the auxiliary agent comprises the following components by mass percentage: inorganic salt (10% of phosphate, 5% of carbonate, 5% of silicate) and organic auxiliary agent (3% of carboxymethyl cellulose, 1% of sodium toluenesulfonate ), anti-caking agent 1%.

[0025] The preparation steps are image 3 shown;

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

Embodiment 2

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

[0028] 2.1. Purpose of the experiment

[0029] By measuring the changes of soil porosity and soil field water holding capacity before and after use, the change of soil porosity reflects the improvement effect of the sample on the soil structure, and the field water holding capacity value reflects the size of the soil water holding capacity and the improvement of the sample to the 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 by dividing it into two pieces, one piece was irrigated with the sample (200g per mu, dissolved in 200-400kg water first, and then flushed with water), and the other piece was irrigated with water. One week later, soil was taken from both the treated field ...

Embodiment 3

[0047] Embodiment 3: the influence of sample on the growth of wheat seedlings after improving the soil

[0048] 3.1 Purpose of the test

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

[0050] 3.2 Test conditions

[0051] Room temperature (20°C).

[0052] 3.3 Test steps

[0053] Control (CK): 500g of soil is loaded into a 500ml beaker, 8 grains of wheat are sown in each beaker, and water is poured until the soil is moistened;

[0054] Treatment (sample): put 500g soil and 1g sample in a 500ml beaker, mix evenly, sow 8 grains of wheat in each beaker, and pour water until the soil is moist;

[0055] Each treatment repeats 20 groups, and after germination, keep the soil moist and cultivate for 8 days, each group randomly selects 5 plants, and carries out investigations on shoot length, root length and root number, the results are as follows: figure 2 , Tab...

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.
