The growth and development of peanuts are affected
[0004] Chinese patent application CN107114105A discloses a method for repairing peanut continuous cropping obstacles by pressing green wheat technology. The method repairs continuous cropping obstacles for peanuts by pressing green wheat to increase production and income. However, the increase rate of this method is relatively small, and the mortality rate of peanuts is reduced. smaller
At present, a single crop is used to repair peanut continuous cropping obstacles through crop pressing, and the effect needs to be improved. Moreover, after the existing green pressing, fresh plants are rotated into the soil, which is easy to cause odor and is easy to damage. Peanuts cause infection, germs and other problems

Embodiment 1
[0028] A method for releasing peanut continuous cropping obstacles through joint pressing of rape and onion, comprising the following steps:
[0029] (1) Onion planting: choose red onion varieties, sow at the end of September, the sowing depth is 0.5-0.8 cm, the sowing width is 20 cm, and the interval between two rows of onions is 35 cm;
[0030] (2) Rapeseed planting: Select high-quality, disease-resistant, high-yielding, saline-alkali-resistant, low-temperature-resistant winter varieties, sow at the end of September at a depth of 2-3cm, generally no later than October 5th. in the space between the two rows of onions;
[0031] (3) Green pressing: When the rape enters the full flowering stage, use a rotary tiller to press the rape and onion plants as a whole, and spray the subsequent inhibitor on the surface after pressing;
[0032] The pressed green follow-up inhibitor is made up of the following percentage raw materials: 0.3% of zinc chloride, 25% of activated carbon, 3.5% ...

[0042] A method for releasing peanut continuous cropping obstacles through joint pressing of rape and onion, comprising the following steps:
[0043] (1) Onion planting: choose red onion varieties, sow at the end of September, the sowing depth is 0.5-0.8 cm, the sowing width is 35 cm, and the interval between every two rows of onions is 40 cm;
[0044] (2) Rapeseed planting: Select high-quality, disease-resistant, high-yielding, saline-alkali-resistant, low-temperature-resistant winter varieties, sow at the end of September at a depth of 2-3cm, generally no later than October 5th. in the space between the two rows of onions;
[0045] (3) Green pressing: When the rape enters the full flowering stage, use a rotary tiller to press the rape and onion plants as a whole, and spray the subsequent inhibitor on the surface after pressing;
[0046] The pressed green follow-up inhibitor is composed of the following percentage raw materials: 0.2% zinc chloride, 30% activated carbon, 4% m...

Abstract
The invention belongs to the technical field of crop planting and particularly relates to a method for removing successive cropping obstacles of peanuts by combining rapes with onions for green manureburying. The method is realized through the following steps of firstly, planting the onions and the rapes, then carrying out rotary tillage and green manure burying after the rapes enter a full flowering period, sowing the peanuts after an inhibitor is sprayed, and harvesting the peanuts through field management. According to the method, the rapes and the onions are combined for green manure burying, soil texture can be improved after green manure burying, soil texture is loose and fertile, and the organic matter content is increased; meanwhile, after green manure burying is carried out, theprobability of diseases and pests of the peanuts can be obviously reduced, the yield of the peanuts can be increased, and the quality of the peanuts can be improved; through a green manure burying technology, trace elements required in the growth and development process of the peanuts can be provided, and the successive cropping obstacles of the peanuts can be overcome. Meanwhile, the self-toxic resistance of peanut plants can be improved, the stress resistance of the peanuts can be enhanced, and no peculiar smell can be generated after green manure burying.
Description
technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a method for removing obstacles to continuous cropping of peanuts through joint pressing of rapeseed and onions. Background technique [0002] Peanut is an important oil crop and economic crop in my country. The annual planting area of peanut is 70 million mu, with a total annual output of about 17 million tons. Among the main oil-producing crops, the area is the third, and the total output and oil production per unit area rank first. . Peanut is a kind of crop that is more sensitive to continuous cropping, and the yield of pods decreases by 19.8%-33.4% after 2-3 years of continuous cropping, and the quality decreases. [0003] Due to the drought-resistant and barren-resistant characteristics of peanuts, in the hilly and dry land in the old peanut production area, it can still obtain a certain income compared with other crops, so it has to be cropped continuou...
