4. Pick the seeds in mid-August, control the vegetative growth, and ensure that the young fruits grow into big ones before pulling out the seedlings.

Strengthen pest control to ensure the healthy growth of plants and fruits. First, insect-proof nets are installed at the upper and lower vents to prevent pests from entering the greenhouse from the vents. If aphids, whiteflies, cotton bollworms, tobacco budworms and other pests have entered the room to harm plants, they should be killed in time. Second, we should pay attention to the prevention and control of leaf mold, early blight, gray mold, soft rot, canker and other diseases.

Both protective tomatoes and exposed tomatoes are mostly replaced by high temperature, water and diseases. Tomatoes are in the off-season of 8-7 months, so the goods are cheaper and the economic benefits are good.

1. Keep the membrane, dig the drainage pipe, and be waterproof and rainproof. The top of the top and the bottom of the bottom make the air in the shed unobstructed, and can heat the gas in time to reduce the indoor temperature and air humidity. In addition, the film has caused aging pollution, and the light transmittance has dropped to about 50%. It can exert the cooling temperature, and the temperature can be reduced by about 3℃ when it falls off. Always keep it in a suitable temperature range suitable for tomato growth and development. Conventional pollination and fruit setting guarantee of tomato.

2. Refine germination and prevent vegetative growth, which will lead to birth conflict and fruit drop. Before mid-June, apply a large amount of organic fertilizer, 60-80 kg per border, to promote soil aeration, enhance root activity, improve absorption capacity and maintain vigorous growth.
