At present, the value of greenhouse vegetable production is an important period for the production of melons and solanaceous vegetables. It is also a period of serious pests and diseases, reminding the majority of vegetable growers to do the following work:
Production management
First, according to the weather changes, cover film insulation and film ventilation to cool, to adjust the temperature and humidity in the shed to meet the needs of vegetable growth and development. At present, the temperature is still high, and the soil in the greenhouse is relatively dry. It is necessary to strengthen the application of fertilizer water to meet the needs of fruit growth and development.
The second is to strengthen water and fertilizer management. At this time, it is the vigorous growth period of the solanaceous vegetables. The fertilizer needs a large amount of water. It is necessary to timely carry out the top dressing and the leaf top dressing, and appropriately supplement the potassium fertilizer and the calcium fertilizer to promote the formation and expansion of the fruit.
The third is to strengthen pest control. During this period, the most common diseases were gray mold, viral disease and powdery mildew. The main pests are aphids, whitefly and spotted fly.
Fourth, the weeds around the farmland should also be included in the prevention and control, clean up the pastoral, minimize the number of remaining, and reduce the base of the coming year.
Disease prevention
1. Botrytis cinerea: It can be controlled by 50% speed Keling WP 600 times solution, ash must (1500% solution), 80% pyrimethanil isocarbazone 800 times solution.
2. Viral disease: First of all, we must eliminate flying insects (mainly aphids, whitefly), and use sticky insect boards and insect nets. Secondly, it is necessary to remove weeds in time and remove the central diseased plants. The third chemical control can be selected: kebao, virus A, phytopathology, scorpion venom 110 and other rotation drugs, foliar spray prevention.
3. Powdery mildew: Powdery mildew is sensitive to sulfur preparations, and can be controlled by foliar spray of white powder rust 1+1, ether phenol, acacia and copper acid.
Pest control
1, physical control: can be attached to the sticky insect board, insect net.
2, chemical control: can choose 1.8% 蚜螨克星乳油 1000 times or 5% é”劲特1500 times plus 10% imidacloprid 1000 times or 1.5% avermectin EC 1500 times spray control. With sufficient water volume, spray the spray on the front and back of the blade, 7-10 days, and the various chemicals should be alternately rotated.
