Embodiment 1

[0009] A wheat manganese-zinc-selenium fertilizer seed dressing agent contains the following materials in 100 parts by weight: 53.295 parts of MnS0 4 ·H 2 0, 26.7 parts ZnS0 4 ·7H 2 O, 10 parts of phoxim, 10 parts of drought resistance agent, 0.005 parts by weight of Na ２ SeO 3 . The formula is mainly used for sowing soil with selenium content less than 0.4mg / kg, which can increase wheat yield by 8.56% and wheat seed selenium content by 7.1%.

Embodiment 2

[0011] A kind of wheat manganese zinc selenium fertilizer seed dressing agent, with 100 parts by weight, contains following material 53.297 parts MnS0 4 ·H 2 0, 26.7 parts ZnS0 4 ·7H 2 O, 10 parts of phoxim, 10 parts of drought resistance agent, 0.003 parts by weight of Na ２ SeO 3 . The formula is mainly used for sowing soil with a selenium content of less than 0.4-0.8 mg / kg, which can increase wheat yield by 9.12% and increase the selenium content of wheat seeds by 5.08%.

Embodiment 3

[0013] A kind of wheat manganese zinc selenium fertilizer seed dressing agent, with 100 parts by weight, contains following material: 53.3 parts of MnS0 4 ·H 2 0, 26.7 parts ZnS0 4 ·7H 2 O, 10 parts of phoxim, 10 parts of drought resistance agent. This formula is mainly used for sowing soil with selenium content greater than 0.8mg / kg, which can increase wheat yield by 9.87%.

Abstract

The invention discloses a Mn-Zn-Se fertilizer seed dressing agent for wheat and meets the requirement that the wheat needs to supplement trace elements Mn and Zn in a growth process. In terms of 100 parts by weight, the seed dressing agent comprises the following substances: 53.299-53.293 parts of MnSO4*H2O, 26.7 parts of ZnSO4*7H2O, 10 parts of phoxim, 10 parts of a drought-resistant chemical and 0.001-0.007 parts of Na2SeO3. The seed dressing agent has the advantages that control of soil insects and improvement of the drought resistance of seeds are realized while yield increase and Se enrichment of the wheat are realized, planting is convenient, and the seed dressing agent is safe, environment-friendly and multiple-effect.

Description

technical field [0001] The invention relates to a seed dressing agent for crops, in particular to a manganese-zinc-selenium mixture seed dressing agent for wheat planting. Background technique [0002] Wheat occupies an important position in the grain structure and is very popular among people for its rich nutrition. Manganese has a great influence on the vegetative growth and reproductive growth of wheat, mainly in: it helps to increase the chlorophyll of wheat, enhances the ability of material transformation and accumulation, promotes the growth of wheat root system, makes it grow vigorously, and obviously improves the resistance of wheat. Cold and drought resistance, and promote the transfer and accumulation of nutrients from the stem to the fruit. Manganese plays an important role in the formation, accumulation and operation of carbohydrates in crops, as well as the redox process in crops, and can promote the growth and development of crops. Zinc fertilizer has wide ap...
