Embodiment 1

[0025] 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;

[0026] 10-12 days before the color pepper planting, transplant the wrinkled-leaf kale whose central leaves are purple; plant a row of kale in the middle of the small row of the planting row, with a plant spacing of 30cm; Seedlings are planted in holes.

[0027] The seedlings of kale are raised on plug trays. The substrate is composed of peat: carbonized rice husk: vermiculite in a volume ratio of 2:1:1. Kale is raised 30 days earlier than peppers. 1-2 days before kale is transplanted, use 50% Mix 12.5g of dinotefuran 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 medicinal solution.

Embodiment 2

[0036] 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 15, 2014 and planted on September 1. The variety was Huangtaiji. There are 2 treatments in the experiment, except for the required measures, other management measures are exactly the same.

[0037] Processing 1: Carry out according to the technical scheme of embodiment 1.

[0038] Treatment 2: Cultivate colored peppers according to the following method, and adopt existing chemical methods to control thrips. The specific technical scheme is as follows: when the color pepper is transplanted, use 12.5g of 50% dinotefuran water-dispersible granules mixed with water 30kg 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 dinotefuran in the case of horses. The planting density of colored p...

Embodiment 3

[0041] Example 3, colored peppers are cultivated in autumn and winter in a solar greenhouse at a certain vegetable base in Shouguang, Shandong. It was sown on July 25, 2015 and planted on September 10. The variety is Hongyingda. Three treatments were set up in the experiment, except for the required measures, other management measures were exactly the same.

[0042] Processing 1: Carry out according to the technical scheme of embodiment 1.

[0043] Treatment 2: Except that the substrate for kale seedlings is peat: vermiculite at a volume ratio of 3:1 and carbonized rice husks are not mixed in the kale planting hole, other measures are the same as treatment 1.

[0044] Treatment 3: Do not spray the mixed aqueous solution of the fennel extract of the repellent plant and chitin except 1-2 days before planting, and spray the seedlings of colored peppers with the mixed solution of fennel extract and chitin 30-40 days after planting. Except for the mixed aqueous solution, other me...

Abstract

The invention discloses a method for preventing and controlling color pepper thrips in a sunlight greenhouse. Color peppers are cultivated in the sunlight greenhouse according to large and small rows,the large row spacing is 80cm, and the small row spacing is 70cm; Brassica oleracea var. acephala f. tricolor is transplanted 10-12 days before field planting is performed on the color peppers, a rowof Brassica oleracea var. acephala f. tricolor is planted in the middle of small rows of field planting rows, and the plant spacing is 30cm; plug seedling raising is performed on the Brassica oleracea var. acephala f. tricolor by adopting a substrate containing carbonized rice husks, carbonized rice husks are applied additionally into field planting holes, a dinotefuran liquid pesticide is adopted to dip hole trays and root irrigation is performed; 1-2 days before field planting is performed on the color peppers and 35 days after field planting is performed, a mixed aqueous solution of a repelling plant extract and chitin is sprayed to leaf surfaces. The method provided by the invention utilizes the trapping plant and the directional concealment application technology to kill the thrips before the thrips spread 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 mainly-planted crops can be realized, and food safety and ecological safety can be guaranteed.

Description

technical field [0001] The invention relates to a method for preventing and controlling pests of colored peppers, especially a method for preventing and controlling thrips on colored peppers that can reduce the use of chemical pesticides and realize non-contact chemical control of main crops. It is especially suitable for the cultivation of colored peppers in autumn and winter in solar greenhouses, and belongs to Field of Plant Protection Planting Technology. Background technique [0002] Thrips are insects that live on plant sap. The larvae are white, yellow, or orange, and the adults are brown or black. Ingestion can cause leaf and flower damage. Thrips are small, agile, and able to fly and jump. They eat the stems, leaves, flowers, and fruits of plants, causing the plants to wither. They also transmit a variety of viruses, including the notorious spotted wilt virus. In recent years, the pest damage has increased year by year. Due to the fast reproduction speed of the i...
