High-yield and cost-saving simple cultivation method for large-group small-entity summer sowing foxtail millet

Abstract

The invention provides a high-yield and cost-saving simple cultivation method for large-group small-entity summer sowing foxtail millet. The high-yield and cost-saving simple cultivation method aims at achieving the mechanical wide-ridge plantation, simplifying procedures and reducing cost. The method includes the steps of selecting a ten-line wheat seeding machine with the sowing width of 200 cm; sequentially blocking seed discharge holes of the ten-line wheat seeding machine in an alternate mode from left to right, wherein the average line spacing is 40 cm; grasping the effective rainfall opportunity after the wheat harvest to complete the rotary tillage procedure, the sowing procedure and the pressing procedure at a time through the wheat sowing machine before the last ten days of June for the regions which have the accumulated temperature larger than or equal to 10 DEG C and have the temperature of about 1800 DEG C to 2000 DEG C during the period between the time when the wheat harvest is completed and the first ten days of October; spraying weed killers after sowing and before emergence or after emergency; adopting the thinning-free and final singling method when 3 to 5 main leaves appear on each millet seedling; conducting topdressing with 10 kilograms of urea in each mu at the elongation state through an intertillage soil moisture preservation and topdressing machine; conducting harvesting through a wheat harvester; reducing the speed of a draught fan system of the wheat harvester till grains can not be blown away.

Description

technical field [0001] The invention relates to a high-yield, cost-saving and simple cultivation method of summer-sowed millet with large groups and small individuals. Background technique [0002] my country's Huanghuai wheat region is rich in light, temperature and water resources in summer, which can realize two crops a year. In the planting structure of this area, there is a long history of re-sowing millet after wheat harvesting, but due to the traditional cultivation methods of millet planting, there are thinning, weeding, artificial topdressing during the growth period, and manual cutting, tying, transportation, cutting ears, Grind. Traditional cultivation methods are complicated and labor-intensive, which is the main reason why the production cost of millet is significantly higher than that of other crops. Therefore, the area of ​​millet sown in summer has shown a downward trend, leading to a continuous rise in the price of millet. In recent years, research on mil...

Problems solved by technology

The above-mentioned technologies violate the growth law of millet "mass growth" (a single grain is small, the force of germination is weak at the top of the soil, and more grains are easy to emerge at the top of the soil together), which often results in poor seedling emergence; after entering this century, Sun Meirong developed the M5 preparation, which can make the millet germinate normally when treated with the preparation, and die automatically when the two leaves unfold. At the same time, the 1:1.86 normal seed (A ) accounts for 35% of the mixed sowing amount of M5 preparation treated seeds (B) and normal seeds (A) is the optimal ratio of field sowing [A / (A+B)×100%]

The disadvantage of this technology is that the seedling retention is not as uniform as artificial thinning, and the mixed seeding ratio provided is difficult to adapt to different drought years and different moisture content plots

Although there are many studies on harvesting machinery and equipment, most of them are not ideal due to the "ear entanglement" between rows.
