Problems solved by technology

These weeding methods are simple to operate, easy to master, and harmless to vegetables and the environment. They have irreplaceable advantages over other weeding techniques, but they take a long time and require a lot of labor. With the transfer of rural labor to cities, the wages of rural labor continue to rise. According to According to the survey, the wages of the labor force engaged in general agricultural activities are 120 yuan / person / day, which undoubtedly increases the input cost and reduces the benefits of vegetable cultivation

Embodiment 1

[0020] Implementation time: May 12 to June 11, 2014.

[0021] Implementation location: Four Seasons Sharing Organic Farm Greenhouse Area P 28 .

Embodiment approach

[0022] Implementation plan: adopt the "pumpkin-choy sum" crop rotation method, and set up a test field and a control field in the implementation, both with an area of ​​0.3 mu. The cultivation form of the test field is "dense planting and weed control":

[0023] 1) After the pumpkins are harvested, perform the first rotary tillage with a depth of about 20cm, and then spray the biogas slurry. When the weeds grow to about 5cm, perform the second rotary tiller, and then "spray the biogas slurry in the field - rotary plowing” cycle 3 times.

[0024] 2) Transplant the cabbage in the seedling shed to the prepared field, 2 trees / hole, a total of 88,000 trees / mu.

[0025] 3) After harvesting, count the weight of weeds (including grass roots) and Chinese cabbage (except vegetable roots) in each square meter of field. The survey method adopts 5-point sampling method, and the area of ​​each point is 1m 2 .

[0026] In the control field, the conventional tillage method was adopted for ...

Embodiment 2

[0029] Implementation time: May 28 to July 04, 2014.

[0030] Implementation location: Four Seasons Sharing Organic Farm Greenhouse Area P 13 .

[0031] Implementation plan: adopt the "winter melon-maranth" crop rotation method, and implement the experimental field and control field in the implementation, with an area of ​​0.3 mu. The cultivation form of the test field is "dense planting and weed control":

[0032] 1) After the wax gourd is harvested, perform the first rotary tillage with a depth of about 25cm, and then spray the biogas slurry. When the weeds grow to about 5cm, perform the second rotary tiller, and then "spray the biogas slurry in the field - rotary plowing" cycle 2 times.

[0033] 2) Sow amaranth seeds evenly in the well-conditioned field, 0.7kg / mu.

[0034] 3) After harvesting, the weight of weeds (including grass roots) and amaranth (except vegetable roots) in each square meter of field is counted. The survey method adopts 5-point sampling method, and t...

Abstract

The invention belongs to the technical field of crop cultivation management, and more specifically relates to a method for preventing and controlling weeds suitable for organic vegetable cultivation. The method includes successive rotary tillage for weed control, dense planting for weed control or intertillage for weed control. Repeat the "Field Spraying Biogas Slurry-Rotary Tilling" 2-5 times in the stubble gap, remove weeds to the maximum extent during the stubble gap period, and then choose dense planting for weed control or intertillage for weeding according to the growth cycle of the crops cultivation. On the basis of inheriting the traditional weeding technology, the method develops a more profitable weed control technology, reduces labor costs, and improves the economic benefits of organic planting.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation management, and more specifically relates to a weed prevention and control method suitable for organic vegetable cultivation. Background technique [0002] Farmland weeds are an integral part of the agricultural ecosystem, which competes fiercely with crops and affects agricultural production directly or indirectly. The main hazards include: competing with crops for water, nutrients, light and space, spreading pests and diseases, and reducing yield and quality. The crop loss caused is second only to diseases and insect pests. [0003] In recent years, with the improvement of living standards, people's requirements for vegetables have gradually exceeded that of food, and their economic value is much higher than that of food. Due to the wide variety of vegetables, various planting methods, fast stubble fall, high multiple cropping index, good soil, water and fertilizer conditions, the veg...
