Millet-dicranostigma leptopodum multiple cropping planting method

Abstract

The invention relates to a millet-dicranostigma leptopodum multiple cropping planting method. The method comprises the following steps that S1, in the middle ten days of June, after watering and moisture formation or raining, when the soil moisture content is appropriate, 200kg/mu-300 kg/mu of organic fertilizer are applied at the bottom, 30kg/mu-40 kg/mu of compound fertilizer is applied in a combined manner, drought-resistant millet varieties are sown, matched herbicide is sprayed in the 3 leaf stage-5 leaf stage of millet seedlings for thinning and weeding, and when the millet seedlings are 35 cm-40 cm, urea or compound fertilizer is dressed by 8 kg/mu-10 kg/mu in combination with intertillage; S2, in the middle ten days of August, the dicranostigma leptopodum seeds are scattered into a grain field, and the seed scattering amount is 1.5 kg/mu-2.0 kg/mu; S3, the millet is harvested at the end of September; S4, in the next year, in March, the dicranostigma leptopodum emerges, topdressing is conducted while rain or watering is conducted in late March, 3 kg/mu-5 kg/mu of urea or compound fertilizer is applied in a spreading mode, seeds and plants of the dicranostigma leptopodum are harvested from the end of May to the beginning of June, and the plants are air-dried or processed to be used as medicine; and S5, the millet is sown again in the middle ten days of June; and crop rotation planting is conducted on the two crops according to the steps. By means of the method, the millet yield and the benefit of yield per mu can be increased, and the problem that dry land is exposed is solved.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for multiple planting of millet and bald sore flowers. Background technique [0002] Multiple cropping is a method of planting and harvesting more than one crop a year on the same cultivated land. There are multiple cropping methods such as sowing three crops in two years, two crops in one year, and three crops in one year. The methods of multiple cropping include: (1) multiple sowing, that is, sowing the subsequent crop after the previous crop is harvested; (2) multiple planting, that is, transplanting the subsequent crop after the previous crop is harvested; , Sowing or planting the following crops between the rows and between the belts. Expanding the multiple cropping area and increasing the multiple cropping index are effective measures to make full use of climate resources and land resources and increase the output and total amount of unit cultivated land ar...
