Embodiment 1
[0015] Experimental location: Experimental Base of Banana Vegetable Research Institute, Dongguan City, Guangdong Province
[0016] Experiment time: September 22, 2014
[0017] Cabbage variety: dark green thick moss cabbage
[0018] Arrangement of the rainproof shed: the rainproof shed includes a cuboid main body and an arched roof on it. The vaulted roof has a curved top surface and curved side surfaces arranged on the main body.
[0019] Build a rainproof shed on the selected field with a steel frame. The length of the main body of the cuboid is 40m, the width is 5m, and the shoulder height is 2.5m; the curved top surface is covered with a film.
[0020] The rainproof shed is set as follows: 2 treatments:
[0021] Treatment 1, the sides and curved sides of the main body of the rainproof shed are vacant for ventilation;
[0022] Treatment 2, the side and curved sides of the main body of the rainproof shed are equipped with insect-proof nets;
[0023] At the same time set ...
Embodiment 2
[0036] In July 2013 (there was a lot of rain during the test period, rainy season) and October 2014 (no rain during the test period, dry season), respectively, planted Chinese cabbage in the rain-proof shed, and investigated the impact of rainfall on the yield and product storability of the rain-proof shed. sexual influence.
[0037] The processing settings are as follows:
[0038] Treatment 3, the sides and curved sides of the main body of the rainproof shed are vacant for ventilation;
[0039] Treatment 4, the side and curved sides of the main body of the rainproof shed are equipped with insect-proof nets;
[0040] At the same time set open field control.
[0041] (1) The impact of rain-proof shed cultivation on the yield of Chinese cabbage
[0042] Statistical treatment 3, treatment 4 and the open field control yield records of Chinese cabbage cultivation in rainy season and dry season are shown in Table 3.

Abstract
The invention provides a Chinese flowering cabbage cultivation method capable of reducing pesticide dosage. The method comprises the steps of building a steel-frame rainproof canopy on a Chinese flowering cabbage planting field, and covering the top of the rainproof canopy with a thin film, and spraying pesticides, such as rotenone and Emamectin benzoate, once in the germination period of Chinese flowering cabbages, so as to kill larvae of flea beetles, plutella xylostella, cabbage caterpillars and the like, wherein the length of the rainproof canopy is 30-50m, the width of the rainproof canopy is 4-7m, and the shoulder height is 2-3m. According to the Chinese flowering cabbage cultivation method capable of reducing the pesticide dosage, provided by the invention, the dosage of the pesticides can be decreased by over 66.6%, meanwhile, the insect leaf ratio of the Chinese flowering cabbages can be kept lower, the integrity of leaves is good, and the quality of appearance is good; the Chinese flowering cabbage cultivation method is free from influence of rainy weather, the consumption of seeds and the pesticides are lowered, the yield is high, the quality of products is good, and the multiple-cropping index is high, so that the Chinese flowering cabbage cultivation method is a practical method for increasing both production and income of farmers and maintaining the yearly supply of the Chinese flowering cabbages.
Description
technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cabbage cultivation method that reduces the use of pesticides. Background technique [0002] There is a habit of growing and eating Chinese cabbage all year round in Guangdong, and the demand for Chinese cabbage is huge. The high temperature and high humidity in Guangdong area lead to frequent occurrence of diseases and insect pests. The cultivation of Chinese cabbage heart is always harmed by flea beetles, diamondback moths, cabbage caterpillars, etc., and the appearance of the products is seriously affected. Vegetable farmers spray pesticides every now and then, resulting in a serious problem of pesticide residues in cabbage. Although the emergence of new high-efficiency and low-toxicity pesticides has reduced the damage to a certain extent, it cannot fundamentally solve the problem. Contents of the invention [0003] In order to overcome the deficiencies of the ...
