A kind of millet seeding control method

Abstract

The invention discloses a millet seeding quantity adjusting and controlling method which aims to achieve the purposes of being low in cost, simple in technology and high in operability. The method includes the steps that a wheat rotary tillage, seeding and compacting all-in-one machine is used for sowing millet, and the seeding quantity of the millet is adjusted and controlled; a seed discharging box cover A and a seed discharging box cover B of a trapezoid structure are manufactured first; the lower bottom face of each box cover is small and the upper bottom face of each box cover is large; a seed discharging hole penetrating through the upper bottom face and the lower bottom face is formed in the middle of one side of the seed discharging box cover A; the seed discharging box cover A covers a seed discharging box used for sowing and discharging seeds in a seed box of the wheat rotary tillage, seeding and compacting all-in-one machine, and the seed discharging box cover B covers a seed discharging box in which seed sowing and discharging are not needed; the seeding quantity, the seeding line spacing and the seeding line number are determined according to the two modes of spring seeding of large groups and wheat stubble remedy aerial seeding of large groups; then the seeding quantity W needed in certain area is calculated according to the formula of W=[(M / 666.7)*(b*a*pi*d*n)]*0.75; when a seed discharging wheel is adjusted to adjust the seeding quantity to be a needed seeding quantity, a seed discharging shaft adjusting valve and a hoop are locked, and the seeding quantity is prevented from being changed in the operating process.

Description

technical field [0001] The invention relates to a method for regulating the sowing amount of millet. Background technique [0002] One of the main agricultural links of millet production is to carry out artificial thinning at the 3-5 leaf stage, which requires more labor. In recent years, due to "the reduction of the rural labor force and the high labor price" (Ke Bingsheng, China Agricultural University), the troubled situation of millet production has become more prominent. Regarding the thinning-free technology, in the 1970s, fried seeds and normal seeds were used for planting; in the 1990s, millet pelleted seeding technology was applied; 5 Preparation, the preparation can make the millet germinate normally when the millet seeds are treated, and die on their own when the two leaves are unfolded. At the same time, the ratio of normal seeds (A) to M 5 The ratio of 35% mixed sowing rate of preparation treated seeds (B) and normal seeds (A) is the optimal ratio [A / (A+B)×10...
