Reasonable and efficient planting method for wheat stubble sesame

Abstract

The invention discloses a reasonable and efficient planting method for wheat stubble sesame. The planting method guarantees the full stand of rush planting of sesame after wheat harvesting when the soil is damp, is simple and efficient, saves labor and time, is beneficial for later-period sesame growth and development, yield formation and field management and solves the problems that the conflict between rush harvesting and rush planting exists all the time and because high wheat stubble is left in land after wheat harvesting, next-stubble crops can not be cultivated easily. According to the concrete scheme, the wheat stubble is kept at the original position after wheat harvesting, damage to the granular structure of the land and loss of the soil moisture content due to high-intensity mechanized cultivation are reduced, wheat straw is cleared out, and grain husks are left in the land; a rotary cultivator carries out rotary cultivation and soil aeration between wheat stubble lines; base fertilizer is sufficiently applied in the fertilization mode of combining quick-acting fertilizer and controlled-release fertilizer, sesame seeds are sown in line, the seeds to be sown are treated with insecticide like carbendazim, and a herbicide is sprayed after sowing to close weeds. Inter-cultivation is not needed in the whole cultivation process, so that labor is saved, the sesame yield and the fertilizer utilization ratio are increased, and the planting method is worthy of application and popularization.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a reasonable and efficient planting method of wheat stubble and sesame suitable for northern regions. Background technique [0002] Sesame is an ancient oil-bearing crop, which belongs to the family Flaxaceae, and is known as the "king of oil-bearing crops". Sesame seeds have an oil content of 50-60%, and are rich in various nutrients such as protein and minerals, and natural antioxidant substances such as sesamol and sesamin. Sesame and its products have high application value and are deeply loved by people. [0003] In North China, a two-crop farming system is implemented a year, and wheat is used to planting in winter. All wheat is harvested by the combine harvester, that is, the integration of harvesting and threshing. After harvest, the stubble remains high, and all the straw remains in the field. The treatment of the straw and stubble is a thorny problem that pl...

AI Technical Summary

Problems solved by technology

This method has many steps to deal with wheat stubble, which is difficult to deal with, and the cost of mechanical cultivation is high, time-consuming and labor-intensive, which will easily cause soil moisture to run out, delay farming time, and cannot achieve early harvesting of wheat sowing.

Delayed sesame planting or too late sowing date will affect the late growth of sesame and affect the yield potential of middle and late maturing high-yielding types

And a large amount of wheatgrass is deeply buried in the soil and competes with the seedlings for nitrogen, which affects the growth of sesame seedlings in the early stage

[0006] 3. Direct cultivation Because the sesame seeds are young and the top soil force is weak, this method cannot ensure that the sesame seedlings are sown in one go, and the seedlings are weak and uneven, which will easily lead to low yield of sesame seeds

Repeated fertilization is time-consuming and labor-intensive, and excessive use of fertilizers can easily cause water and soil pollution
