The prevention and control of tomato damage and the improvement of tomato production and benefits can take the following five measures.
One, ridge load. The flat ridge is a ridge planting. If it has been planted flat, it can be 2-3 times burial to make the ridge heart become a ridge back, so that the ridge back becomes a glutinous heart, but to prevent a single cultivating soil too thick, affecting the absorption capacity of the root system.
Second, picking up the heart and renovating the technology. Changing the traditional single-dry or double-dry pruning method is a new tipping and head replacement technology. When the first and second inflorescences are set, the second and third inflorescences appear, leaving 2-3 leaves topping on them. The first lateral bud that grows under the first inflorescence is used instead of the trunk; after 2-3 inflorescences are also planted, the lateral buds are selected as the main trunk in the middle of the trunk, so that the continuous picking of the heads can stimulate the renewal of the plants. .
Third, timely supply of water and fertilizer. The soil moisture in the field should be basically the same. Usually, water is poured in about 7 days, and 5 kg of compound fertilizer is applied per acre for 15-20 days. At the same time, potassium dihydrogen phosphate solution can also be sprayed on the leaves.
Fourth, remove water in a timely manner. In hot season, watering should be followed by pouring in the morning and evening when it is cool.
Fifth, timely prevention and control of pests and diseases. During the summer of tomatoes, the diseases mainly include diseases and virus diseases. For the disease, 500 times mixture of carbendazim and mancozeb, or thiophanate-methyl and 800-fold mixture of treprolasin should be sprayed every 10-15 days. The effect of alternate use of the two is better; for virus diseases, 40% Leko cream 1500-2000 times liquid can be sprayed in time to eliminate aphids to prevent transmission, and spray once every 7-10 days before onset. Potassium manganate solution to prevent; during the summer insect pests mainly bollworm, corn borer, etc., in the peak period of their eggs, timely spraying dimethoate, pyrethroid insecticides to prevent and control.
