Problems solved by technology

In recent years, with the development of the enzyme preparation industry and the in-depth study of soil enzymes, more and more researches have been done on the transformation of soil organic matter and the formation of nutrients by soil enzymes. These studies mainly focus on the composition, activity and function of enzymes in soil. Focused on, not involved in the use of exogenous enzymes and other aspects

Embodiment 1

[0015] Example 1, in Diaogou Village, Baoji Township, Pingchuan District, Baiyin City, Gansu Province, the soil conditions are basically the same, and the sandy land is irrigated by well water to separate A, B, and C into 3 sub-districts with a length of 50m and a width of 30m. The mass ratio of cellulase 40%, invertase 20%, catalase 10%, urease 30%; the mass ratio of compound enzyme preparation in zone B is cellulase 38%, invertase 19%, catalase 11% , Urease 32%.

[0016] The preparation method of the compound enzyme preparation is as follows: the above four enzyme preparations whose enzyme activity and bacteria reach the standard are sent to the mixing tank according to the above ratio, mixed evenly, and then packed by an automatic vacuum packaging machine to obtain the compound enzyme preparation.

[0017] The amount of compound enzyme added in both areas A and B is 6.0kg per mu. The method of mixing with fine sand soil before wheat planting is adopted. Area C does not ap...

Embodiment 2

[0022] Embodiment 2, in Doucheng Village, Shuiquan Town, Pingchuan District, Baiyin City, Gansu Province, select the land in the Yellow Irrigation Area, and the soil conditions are basically the same cultivated land, and separate A, B, and C three small communities with a length of 40m and a width of 35m. The quality of the compound enzyme preparation in A district The ratio is 42% cellulase, 19% invertase, 10% catalase, and 29% urease; the mass ratio of the compound enzyme preparation in area B is 44% cellulase, 19% invertase, 9% catalase, and 28% urease %.

[0023] The preparation method of compound enzyme preparation is the same as embodiment 1.

[0024] The addition amount of biological compound enzyme in the two areas of A and B is set at 7.0kg per mu. It is applied by mixing with the basal manure and seeding the columbine before wheat planting. The compound enzyme preparation is not applied in area C.

[0025] test results:

[0026] Area A: The whole growth period is...

Abstract

The invention relates to a compound enzyme preparation and application thereof to wheat planting. The compound enzyme preparation consists of the following four kinds of enzymes by mass percent: 35-45 percent of cellulase, 15-25 percent of invertase, 5-15 percent of catalase and 25-35 percent of urease. Before wheat is seeded, the compound enzyme preparation is evenly mixed and jointly applied with fine sandy soil or base fertilizers according to 4.0-8.0kg / mu. The compound enzyme preparation has the advantages that the preparation can provide necessary nutrition for the growth of wheat, the germination rate, the straw thickness, the ear length, thousand kernel weight and the like of the wheat can be improved, and the goal of increasing the yield of wheat is achieved.

Description

technical field [0001] The invention belongs to the technical field of biological enzyme preparation application. Background technique [0002] Soil is the basic resource for human survival and the main basis for agricultural development. Most of my country's agricultural production uses a large amount of chemical fertilizers to increase production and income. In the 1980s, the contribution rate of chemical fertilizers to grain production increased by about 35%. In the 1990s and the beginning of this century, the production-increasing benefits of chemical fertilizers declined significantly, and the agricultural ecological environment problems caused by the use of chemical fertilizers became increasingly serious. Due to the extensive use of chemical fertilizers, the content of nitrogen, phosphorus, sulfur and other elements in the soil is generally high, resulting in soil compaction, acidification, and salinization. The ineffective components in the soil are enriched in a lar...
