Embodiment 1

[0040] A method for controlling weeds in potato fields, comprising the steps of:

[0041] Before planting S1 potatoes:

[0042] S11 Deep plowing and plowing: In autumn, agricultural machinery is used to weed and plow the land, and the cycle of deep plowing and plowing is once every three years;

[0043] S12 fertilization: apply decomposed soil and miscellaneous fertilizers after the soil is cultivated in spring;

[0044] When S2 potatoes are planted:

[0045] S21 soil sealing: after the S12 step ends, sow potatoes after spraying herbicide I on the soil surface after ridges;

[0046] S22 Covering with film: After the ridge surface is leveled, black plastic film is covered, and the film and the soil are naturally close;

[0047] After planting S3 potatoes:

[0048] S31 post-emergence stem and leaf treatment: spray herbicide II evenly on the stem and leaf of weeds at the early stage of potato emergence;

[0049] S32 Cultivation and soil cultivation: the first cultivation and...

Abstract

The invention relates to a control method of potato field weed. The method comprises the following steps: S1, before potato planting: S11, deep ploughing to turn up the soil and S12, applying fertilizer; S2, during potato planting: S21, carrying out sealing treatment on the soil; S22, mulching with a film, and S3, after potato planting: S31, carrying out stem and leave treatment after seedling emergence; S32, carrying out cultivation and earthing up; S33, artificial weeding, and S34, carrying out cultivation and earthing up, and S4, carrying crop rotation. The control method of potato field weed has the advantages of high weed control rate, high potato quality, non-pollution and high safety.

Description

technical field [0001] The invention relates to the technical field of comprehensive prevention and control of weeds, in particular to a method for controlling weeds in potato fields. Background technique [0002] In the development of potato industry, potato weeds are becoming more and more harmful. Weeds not only directly compete with potatoes for nutrients, water, sunlight and space, thereby reducing the yield and quality of potatoes. At the same time, weed control in our region currently uses manual weeding methods. The high cost makes potato planting enterprises and farmers miserable. Unbelievable, according to the survey, only manual weeding can increase the cost by more than 130 yuan per mu of land. In addition, due to imperfect weeding technology and insufficient funds, the application of weed control technology in potato fields in our region is very different from place to place and among different farmers, which is not standardized, resulting in increased control ...
