Embodiment 1

[0021] Embodiment 1, the cultivation of cucumbers in autumn and winter in solar greenhouses, the cucumbers are cultivated in rows according to size in solar greenhouses, with a large row spacing of 70cm, a small row spacing of 60cm, and a plant spacing of 35cm;

[0022] 15-20 days before the cucumber planting, transplant and trap the lure plant Mingyuecao; plant a row of Mingyuecao in the middle of the planting row, with a spacing of 22cm; open holes for colonization, and mix 75g of carbonized rice husks in each hole, and plant Mingyuecao in the holes.

[0023] The seedlings of Mingyue grass are raised in plug trays. The substrate is composed of peat: carbonized rice husk: vermiculite in a volume ratio of 2:1:1. Mingyue grass is raised 25-30 days earlier than cucumbers. 1-2 days before transplanting, use 25 Mix 17.5g of %thiamethoxam water-dispersible granules with 30kg of water and dip in the plug for 2-3 minutes, so that the matrix in the plug is completely soaked by the medi...

Embodiment 2

[0030] Example 2. Cucumbers were cultivated in autumn and winter in a solar greenhouse. The location was a cucumber greenhouse in Shouguang, Shandong Province. It was sown on July 20, 2014 and planted on August 18. The variety was Jinza No. 2. There are 2 treatments in the experiment, except for the required measures, other management measures are exactly the same.

[0031] Processing 1: Carry out according to the technical scheme of embodiment 1.

[0032] Treatment 2: Cultivate cucumbers according to the following method, and adopt existing chemical methods to control Bemisia tabaci. The specific technical scheme is as follows: when the cucumber is transplanted, use 17.5g of 25% thiamethoxam water-dispersible granules mixed with 30kg of water to dip the hole plate for 2-3 minutes, so that the matrix in the hole plate is completely soaked by the medicinal liquid. Foliar spraying of thiamethoxam for lice occurrence. Cucumber planting density was the same as treatment 1.

Embodiment 3

[0035] Example 3: Cucumbers are cultivated in autumn and winter in a solar greenhouse at a certain vegetable base in Shouguang, Shandong. Sowed on July 15, 2015, and planted on August 14, the variety is Xinjin 11. There are 4 treatments in the experiment, except for the required measures, other management measures are exactly the same.

[0036] Processing 1: Carry out according to the technical scheme of embodiment 1.

[0037] Treatment 2: Except that the seedling substrate of Mingyue japonica is composed of peat: vermiculite at a volume ratio of 3:1 and that carbonized rice husks are not mixed in the planting hole of Mingyue qingming, other measures are the same as treatment 1.

[0038] Treatment 3: Except that the cucumber seedlings are not sprayed with the mixture of new high-fat film and chitin 1-2 days before planting, and the leaves are not sprayed with the mixture of new high-fat film and chitin 25 days after cucumber planting, other measures are the same as treatment ...

Abstract

The invention discloses a method for preventing and controlling cucumber bemisia tabaci in a sunlight greenhouse. Cucumbers are cultivated in the sunlight greenhouse according to large and small rows,the large row spacing is 70cm, and the small row spacing is 60cm; a trapping plant is transplanted 15-20 days before field planting is performed on the cucumbers, a row of trapping plant is planted in the middle of small rows of field planting rows, and the plant spacing is 22cm; plug seedling raising is performed on the trapping plant by adopting a substrate containing carbonized rice husks, carbonized rice husks are applied additionally into field planting holes, a thiamethoxam liquid pesticide is adopted to dip hole trays and root irrigation is performed; 1-2 days before field planting isperformed on the cucumbers and 25 days after field planting is performed, a mixed aqueous solution of a higher fatty acid-containing complex and chitin is sprayed to leaf surfaces. The method providedby the invention utilizes the trapping plant and the directional concealment application technology to kill the bemisia tabaci before the bemisia tabac spreads to the color peppers, at the same time,the use amount of chemical pesticides can be reduced, the non-contact chemical prevention and control of the mainly-planted crop cucumbers can be realized, and food safety and ecological safety can be guaranteed.

Description

technical field [0001] The invention relates to a control method of cucumber pests, especially a control method of bemisia tabaci which can reduce the use of chemical pesticides and realize non-contact chemical control of main crops. It is especially suitable for the cultivation of cucumbers in autumn and winter in solar greenhouses and belongs to plant protection. technology field. Background technique [0002] Bemisia tabaci belongs to the family Amiptera of Homoptera. Adults and nymphs mainly suck the juice of plants, causing chlorosis, wilting or dead leaves of the affected leaves. At the same time, they secrete honeydew to induce soot, affect the photosynthesis of plants, and make plants grow bad. Bemisia tabaci can also transmit a variety of plant virus diseases. In recent years, the pest damage has increased year by year. Due to the fast reproduction speed of the insect, serious overlapping of generations, wide range of hosts, fast transmission and spread, strong d...
