Embodiment 1

[0024] Embodiment 1, colored peppers are cultivated in autumn and winter in a solar greenhouse, and the colored peppers are cultivated according to size in a solar greenhouse, with a large row spacing of 80cm, a small row spacing of 70cm, and a plant spacing of 50cm;

[0025] 15-20 days before color pepper planting, transplant Mingyuecao; plant a row of Mingyuecao in the middle of the planting row, with a plant spacing of 30cm; open holes for colonization, and apply 75g of carbonized rice husk to each hole, and plant Mingyuecao in the holes.

[0026] The seedlings of Mingyue grass are raised with a plug substrate. The substrate is composed of peat: carbonized rice husk: vermiculite in a volume ratio of 2:1:1. Mingyue grass is raised 30 days earlier than colored peppers, and 25% of Mingyue grass is used 1-2 days before transplanting. Mix 17.5g of thiamethoxam water-dispersible granules with 30kg of water and dip in the plug tray for 2-3 minutes, so that the matrix in the plug tr...

Embodiment 2

[0035] Example 2. Colored peppers were cultivated in autumn and winter in a solar greenhouse. The location was in a greenhouse of colored peppers in Shouguang, Shandong Province. The seeds were sown on July 20, 2014 and planted on September 5. The variety was Hongyingda. There are 2 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: Cultivate colored peppers according to the following method, and adopt existing chemical methods to control Bemisia tabaci. The specific technical scheme is as follows: when the colored pepper 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 solution, and the growth period is determined according to the tobacco. Foliar spr...

Embodiment 3

[0040] Example 3, colored peppers are cultivated in autumn and winter in a solar greenhouse at a certain vegetable base in Shouguang, Shandong. Sowed on July 25, 2015, and planted on September 10, the variety is Huang Taiji. Three treatments were set up in the experiment, except for the required measures, other management measures were exactly the same.

[0041] Processing 1: Carry out according to the technical scheme of embodiment 1.

[0042] 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.

[0043] Treatment 3: In addition to not spraying the mixed aqueous solution of lettuce extract and chitin 1-2 days before planting, and spraying the mixed aqueous solution of lettuce extract and chitin on the leaves for 25 days after planting, other measures Same as 1.

[0044]Acc...

Abstract

The invention discloses a method for preventing and controlling color pepper bemisia tabaci. Color peppers are cultivated in a sunlight greenhouse according to large and small rows, the large row spacing is 80cm and the small row spacing is 70cm; gynura divaricata is transplanted 15-20 days before field planting is performed on the color peppers, a row of gynura divaricata is planted in the middleof small rows of field planting rows, and the plant spacing is 30cm; plug seedling raising is performed on the gynura divaricata 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 is performedon the color peppers and 25 days after field planting is performed, a mixed aqueous solution of a repelling plant lettuce extract and chitin is sprayed to leaf surfaces. The method provided by the invention utilizes the trapping plant gynura divaricata and the directional concealment application technology to kill the bemisia tabaci before the bemisia tabaci 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 color peppers can be realized, and food safety and ecologicalsecurity can be guaranteed.

Description

technical field [0001] The invention relates to a method for preventing and controlling pests of colored peppers, in particular to a method for preventing and controlling Bemisia tabaci which can reduce the use of chemical pesticides and realize non-contact chemical control of main crops, and is especially suitable for the cultivation of colored peppers in autumn and winter in solar greenhouses. It belongs to the technical field of plant protection. 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 gene...
