Cultivating method of tomato trees

Abstract

The invention discloses a cultivating method of tomato trees and aims to realize the long-term growth and disease resistance and high yield of the tomatoes. The method comprises the following steps: disinfection of nutrient soil, cultivation of root stock seedlings, cultivation of scion seedlings of mini-tomatoes and colored tomatoes, grafting, grafted seedling management, field planting to field or greenhouse flowerpots, and shaping, trimming and pruning. Compared with existing tomato cultivation techniques, the cultivating method provided by the invention changes the tomatoes into woody plants and realizes the purposes of cultivating once, growing for many years and rapid growing. The plants can grow to a height of 4-5m in a quarter and the side branches can also be used as the basic branches. The method can completely change the traditional single trunk pruning method, and the number of buds can be increased by 40-60, and a plant has 3-4 trunks. The plants can grow through a summer or a quarter when cultivated in an open field and can bear fruit throughout the year when cultivated in greenhouses. The method can increase the yield by 3-4 times, realizing a yield of 15,000-20,000 kg per mu, and increase the nutrient content by 2-3 times. The varieties have high immunity against the soil infectious disease and cropping cultivation can be achieved.

Description

technical field [0001] The invention relates to crop cultivation techniques, in particular to a method for cultivating tomato trees. Background technique [0002] The tomato growth period is three months, and the longest is no more than six months. At present, the best varieties at home and abroad can only be cultivated for one year. However, it has poor resistance to blight, wilt, and root-knot nematode diseases in high temperature periods, and it cannot resist root rot and other "incurable" diseases that are prone to occur in low temperature periods. It can only be planted for one season on the same plot, and continuous cropping is not possible. For replanting, it is necessary to carry out 4-5 years of crop rotation with non-nightshade crops, and the infection of unknown soil is serious, and the general dead seedling rate is 50%-70%, which is serious or even impossible. A large number of pesticides are used, and it is difficult to control the occurrence of diseases. The l...

However, it has poor resistance to blight, wilt, and root-knot nematode diseases in high temperature periods, and it cannot resist root rot and other "incurable" diseases that are prone to occur in low temperature periods. It can only be planted for one season on the same plot, and continuous cropping is not possible. For replanting, it is necessary to carry out 4-5 years of crop rotation with non-nightshade crops, and the infection of unknown soil is serious, and the general dead seedling rate is 50%-70%, which is serious or even complete.

A large number of pesticides are used, and it is difficult to control the occurrence of diseases. The latest antibacterial pesticide Nongromycin M18 produced in Shanghai, my country can only be controlled at 70%. In order to solve the occurrence of diseases and crop rotation, farmers have to invest huge sums of money every year. Reconstructing the greenhouse or replacing the soil in a timely manner wastes a lot of manpower, material resources, financial resources, leads to idle temperature difference, and greatly increases production costs
