Embodiment 1

[0035] Example 1 Preparation of Rapeseed Pod Powder and Rapeseed Straw Section

[0036] After harvesting, rape stalks with rape pods (the rapeseed is Zheda 619, which is available in the market) are subjected to conventional drying, that is, after the rape is harvested, it is spread out in the sun for 3 to 7 days, or air-dried in the shade for 7 to 15 days. Rapeseeds were harvested from rape pods, and then the dried rape pods and rape stalks were placed in a 680-type hay cutter (Zhejiang Jinhua Shengshi Hardware Machinery Co., Ltd.) with apertures of 4mm and 8mm respectively for crushing, and the particle sizes were obtained respectively. Rapeseed pods of 0.5 cm in length and rapeseed straws of 3 cm in length and 0.5 cm in diameter; the rapeseed pods and rapeseed straws were further pulverized to 0.05 cm to obtain rapeseed pod powder and rape straw powder.

Embodiment 2

[0038] The rape pod powder, rape pod segment, rape stalk powder and rape stalk segment prepared in Example 1 were taken to carry out the process of weed control in the broccoli field. The specific steps and the content of the experimental treatment are as follows:

[0039] 1. Test location: in the winter and spring broccoli base of Shangpan Town, Linhai City, Zhejiang Province.

[0040] 2. Test time: September to December 2017

[0041] 3. Test variety: Lvxiong 90 (the main variety in Zhejiang, available on the market)

[0042] 4. Experimental content and treatment: Sprinkle rape pods (rape pod segments or powder) and rape straw (rape straw powder) segments to the broccoli field in different ways (see the experimental treatment for details) to control weeds in the broccoli field. The broccoli cultivation process adopts conventional cultivation management methods, and no herbicides are used.

[0043] There were 12 treatments in the test, and each treatment was repeated 3 times. ...

Abstract

The invention discloses a method for controlling and preventing weeds in a broccoli field. The method comprises the steps that rapeseed meal powder is evenly sprayed into the broccoli field on the daywhen the broccoli is transplanted; within the period from the first day to the seventh day after the broccoli is transplanted and survives, the broccoli field is evenly covered with rapeseed straw pieces, and the weeds in the broccoli field are controlled and prevented. By means of the method, not only can the graminaceous weeds, the broad-leaved weeds and the cyperaceae weeds, especially the broad-leaved weeds, in the broccoli field be effectively controlled and prevented, but also the quality of the broccoli can be further improved, and the yield of the broccoli can be further increased.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for controlling weeds in a broccoli field. Background technique [0002] Broccoli, as a nutritious and healthy vegetable today, has become an important target for structural optimization. In the 21st century, Zhejiang, Shanghai, Fujian, Yunnan, Jiangsu, Guangdong and other provinces and cities have developed rapidly and become an important export-oriented vegetable. The annual planting area of ​​broccoli in Taizhou is about 150,000 mu. As one of the leading development bases for exporting broccoli in China, it is mainly produced in winter and spring and exported to Japan in the form of fresh-keeping or quick-frozen, followed by the United States, the Middle East, Europe and ASEAN. In the international market Enjoy a high reputation and become an important pillar industry. [0003] However, as the threshold for importing vegetables in developed countries...
