Description

DESCRIPTION HUS01250 Saline land improver for wheat cultivation

TECHNICAL FIELD The present invention relates to the technical field of a soil conditioner, specifically a saline conditioner for wheat cultivation.

BACKGROUND Wheat is one of the most important food crops in the world. More than 1/3 of the world's population consumes wheat as a staple food. The nutritional value of wheat is very high, with a protein content of 11-14% in the grain (up to 17%-18% in some cases), which is higher than that of ordinary cereal crops.

Wheat yield and quality are the result of the interaction between varietal characteristics (endogenous) and environmental conditions (exogenous). In field production, the living conditions necessary for wheat growth and development, light and temperature are mainly met from the natural environment, while water, air and nutrients, in addition to some from the natural environment, are mainly supplied and regulated by people in the cultivation process. Most of this regulation takes place through the soil. Soil is the basis for wheat growth, and nutrients and water are the material conditions on which wheat grows.

The texture of the soil directly affects the growth and development of wheat. Heavy clay or clay soils are not conducive to wheat germination and seedling development because of their fine texture, compact structure and poor aeration. Sandy soils, with their loose structure, poor water and fertiliser retention capacity, low nutrient content and wide temperature variation, are not conducive to wheat growth and overwintering. The most suitable soil for growing wheat is loam, which has strong water and fertiliser retention capacity and a high phosphorus and potassium content, which is conducive to wheat seedling and root development and has a high yield potential. Soils with a capacity of 1.14-1.365 g/cm* and a porosity of 50-55% are ideal. Such soils are resistant to drought, flooding, fertiliser retention and good arable properties, which helps to improve the quality of the land preparation. Wheat can grow on both slightly acidic and slightly alkaline soils, but the most suitable soil is PH 6.8-7.0, that is, a neutral-responsive soil is appropriate. The salt content of the HUS01250 soil has a large impact on the germination and emergence of wheat. According to the results of local measurements, the total salt content of the general soil layer up to 0.25% is the threshold of salt tolerance of wheat sowing and seedling stage, up to 0.4% above the seed is lost germination capacity, seedlings are seriously inhibited.

Saline land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. The current area of saline land in China is

99.13 million hectares. Most of the formation of alkaline and alkaline soils in China is related to the accumulation of carbonates in the soil, thus the alkalinity is generally high and plants can barely survive in areas with severe saline soils.

At present, saline land improvers for wheat cultivation have not been disengaged from laboratory products suitable for large-scale use, mainly by adding lignite, zeolite, lignin organic matter, gypsum, vinasse, etc. to improve the physical properties of the soil. However, the improvement time is short, frequent applications are required and costs are high.

Therefore, a soil conditioner for wheat cultivation that is suitable for widespread application and has long-lasting efficacy is in urgent need of discovery.

SUMMARY To solve the deficiencies in the prior art, the present invention provides a saline land improver for wheat cultivation to solve the problem of low success rate of existing cultivated wheat in saline land.

To solve the above technical problems, the technical solution of the present invention is as follows.

A saline land improver for wheat cultivation, the components include sulphur powder, grass charcoal, sodium alginate, chrysanthemum, saponaria, mulberry leaf, paniculata, sweet potato powder and eggshell powder.

Further, a saline land improver for wheat cultivation with the following components by weight: 10-20 parts of sulfur powder, 20-30 parts of grass charcoal, 20-25 parts of sodium alginate, 5-10 parts of chrysanthemum, 2-8 parts of saponaria,

mulberry leaves 2-5 parts, Panax notoginseng 2-5 parts, sweet potato powder 5-8 parts, HUS01250 eggshell powder 5-10 parts.

Preferably: 15 parts of sulphur powder, 25 parts of grass charcoal, 22 parts of sodium alginate, 8 parts of chrysanthemum, 4 parts of saponaria, 3 parts of mulberry leaves, 4 parts of panax quinquefolium, 6 parts of sweet potato powder and 7 parts of eggshell powder.

A saline land improver for wheat cultivation as described above is prepared as follows.

Weighing chrysanthemum, saponaria, mulberry leaves and panax quinquefolium according to the above weight, soaking in water at 25-30°C for 2 hours, boiling until boiling and then continuously heating for 20-30 minutes, while annealing and cooling down, filtering the dregs, adding weight of sodium alginate, sulphur powder, grass charcoal, chrysanthemum, saponaria, sweet potato powder and egg shell powder and stirring, drying.

Sodium alginate is weakly acidic and suitable for improving alkaline soils. It has hydrophilic properties and is weakly gelatinous when in contact with water. It improves the soil and at the same time replenishes the nutrients needed for the growth of wheat on a relatively long-term basis.

The interaction between the components of improver increases the survival rate and harvest rate of wheat planting, while retaining water, diluting salt ions in saline land, lowering pH, acting quickly, not requiring long-term planting to improve the soil, and saving costs.

The beneficial effects of the present invention are as follows.

The invention is suitable for use in wheat saline land cultivation. Mixing improver into the soil or spreading it on the tillage layer can neutralize the soil alkalinity, dilute the salt ions in the soil, retain water and store fertilizer, enhance the disease resistance of wheat, and make a good foundation for yield increase.

A saline land improver for wheat cultivation as described above, is prepared by the same method as in Example 1, Validation test: Using the improver described in the present invention, a test of the saline improvement effect was conducted in a test field in Laixi City, Shandong Province, with two test fields, which were numbered as test field No. ! and test field No 2.

Test field No. 1 was divided into six areas, 1-1 to 1-6, test field No 2 was also divided into six areas, 2-1 ta 2-6.

1-1 to 1-6 are the experimental groups, using the improver prepared in Example 3 of the present invention and spreading improver on the tillage layer. 2-1 to 1-6 are the control groups, irrigated with water once before ploughing, sown 4 days after sprinkling and irrigated with water once at the same time after the wheat has entered the secdhing stage. Subsequently, no further irrigation was carned out and observations were made after & days.

The results showed that only 60% of the wheat grown in the control group of 2-1 to 2-6 emerged after sowing. In contrast, the experimental group using the improver described in the present invention had a seedling emergence rate of 84%.

Grading criteria for damage: Grade ©: leaf extension and normal growth: Grade ! a small amount of leaf edge drying or yellowing, Grade 2: 50% leaf and a small amount of stem segment drying or vellowing: Grade 3: more than 80% leaf vellowing and more than 50% stem segment drying; Grade 4: complete death. Salt damage index {9e } = 3 { number of representative grades x number of plantsy{ top grade value x total number of plants x 100%. See Table 1.
