Abstract

The invention discloses a semi-solid-state complex no-tillage dry direct seeding method for crop seeds. The no-tillage dry direct seeding method comprises the following steps: S1, keeping a water layer of 1cm-5cm in a ditch, and paving straws obtained by harvesting preceding crops on a ditch surface; S2, applying a base fertilizer on the ditch surface paved with the straws and cleaning the ditch; S3, seeding the crop seeds on the ditch surface, and mixing the crop seeds with semi-solid-state biomass materials, a compound fertilizer and a biopesticide before seeding before seeding seeds, wherein the mixing mass ratio is that the crop seeds to the semi-solid-state biomass materials to the biopesticide is (1-10) to (70-800) to (1-3), and the moisture content of the semi-solid-state biomass materials is 40%-80%; and S4, after seeding the seeds, keeping the ditch surface at a dry state for 3-7 days. According to the semi-solid-state complex no-tillage dry direct seeding method, tillage and combustion of winter crop straws are not carried out, a whole land of field immersing water is not used for irrigation and the water immerses after the seeding, and the biological benefits are obvious; the working energy consumption is reduced, stubbles are not killed by pesticides, haze is reduced and the irrigation water is reduced.

Description

technical field

[0001] The invention relates to the technical field of crop cultivation, in particular to a no-tillage and dry direct seeding method of a semi-solid composite of crop seeds. Background technique

[0002] According to statistics, my country's total grain output in 2013 exceeded 600 million tons, estimated based on the grain-to-stalk ratio of 1:1.2, plus other crop straws, my country's annual production of straw exceeded 720 million tons. Straw is rich in organic matter, nitrogen, phosphorus, potassium and trace elements. 720 million tons of straw is equivalent to 5.76 million tons of urea, 8.4 million tons of superphosphate, and 8.4 million tons of potassium sulfate.

[0003] Studies have shown that crop straw returning to the field is an effective measure to increase production, generally increasing production by more than 4%. At present, most of the crop straw resources in my country are used as living fuel or burned in the field or dumped in disorder, which...

Embodiment Construction

[0044] A method for no-tillage and dry direct seeding of crop seed semi-solid composites, comprising the following steps:

[0045] 1) Field management before sowing: First, sort out the soil, which can be used as the basis. After the previous crops are harvested, no plowing or irrigation is required, and the soil is in the state of flat soil. It is only necessary to scatter the soil from the ditch evenly on the surface when cleaning the ditch; the width of the side of the stubble field before direct seeding is 180-240 cm, and the width of the ditch is 10-20 cm. 15~30cm deep. Use a combine harvester for harvesting, use the grass-cutting function of the harvester to evenly chop and spread the crop stalks on the car surface; Spread the straw and use the disc trencher to clear the trench.

[0046] 2) Base fertilizer application before sowing: Evenly spread 60% of the total nitrogen fertilizer, 60% of the total potassium fertilizer and 100% phosphate fertilizer on the car surface...
