Tomato-tree cultivating method

Abstract

The invention discloses a tomato tree cultivating method. The steps as follows: sterilizing nutritious earth, cultivating stock seedling, cultivating micro- and color-tomato graft seedling, grafting,managing grafted seedling, etc. It turns the tomato into the woody plant, the growth fast, the plant height able to reach 4-5m, the lateral branch also able to be used as the basic branch, one plant able to remain 3-4 stems, the flower buds increased by 40-60, the nutrition constituent added by 2-3 times. It has high-anti immunization to earth infectious diseases, and can be continuously cropped.

Description

technical field [0001] The invention relates to crop cultivation techniques, in particular to a method for cultivating tomato trees. Background technique [0002] The growth period of tomatoes 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 th...

Problems solved by technology

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 heavy cropping, it is necessary to carry out 4-5 years of crop rotation with non-nightshade crops, and the infection of unknown soil is serious. Generally, the rate of dead seedlings is 50%-70%, and the harvest is even severe.

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. Rebuilding 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
