Non-toxic, bud-rich tomato tree cultivation method for grafting scions

Abstract

The invention discloses a non-toxic, bud-rich tomato tree cultivation method for grafting scions and belongs to the technical field of plant cultivation. The non-toxic, bud-rich tomato tree cultivation method for grafting scions comprises following steps: 1: sterilizing planting substrate; 2: cultivating scions; 3; managing fertilizer and water; 4: controlling diseases and insect pest; 5: grafting. According to the tomato tree cultivation method of the invention, disinfection is carried out on the planting substrate, scion seeds, grafting tools and grafting containers so as to realize the purpose of reducing the pathogen on scions, reduce the disease susceptibility rate of the grafted seedlings, and thereby improve the survival rate of the grafted seedlings; the cultivated tomato trees have strong ability to branch, each leaf axil can generally grow lateral buds, 15 to 20 live lateral buds are picked for use as grafting scions, which reduces cost. After tomato planting, the node position of fruit set decreases obviously, the number of fruiting spikes increases, the yield of tomato increases, and the income of planters is increased.

Description

technical field [0001] The invention relates to a non-toxic multi-bud tomato tree cultivation method for grafting scions, belonging to the technical field of plant cultivation. Background technique [0002] Soil-borne diseases of tomato such as fusarium wilt and bacterial wilt are the main causes of tomato death. In order to avoid this situation, people often choose some varieties resistant to fusarium wilt and bacterial wilt for planting, but due to the few varieties and poor quality, they cannot meet the market demand. In recent years, many tomato rootstock varieties resistant to Fusarium wilt and bacterial wilt have been screened at home and abroad, and the occurrence of tomato Fusarium wilt and bacterial wilt has been greatly reduced or avoided through grafting technology. [0003] Although grafting can solve the occurrence of tomato wilt and bacterial wilt, the seeds used for grafting tomato scions are generally more expensive (1-1.5 yuan / grain). If 1800-2000 strains ...

Problems solved by technology

[0003] Although grafting can solve the occurrence of tomato wilt and bacterial wilt, the seeds used for grafting tomato scions are generally more expensive (1-1.5 yuan / grain)

If 1800-2000 strains are planted per mu, during grafting, if only 1 scion bud is cultivated from 1 scion seed, the input cost of scion seed alone will be 2600-4300 yuan / mu (including the cost of purchasing seeds and grafting loss), such as Including other costs (such as purchasing rootstocks, grafting labor costs, etc.) will be a large batch of expenses, which is difficult for growers to accept

Secondly, when cultivating tomato scions, if the seeds, seedbeds, and grafting tools are not thoroughly sterilized, the tomato scions will be infected with germs before and during grafting, then the infection rate of grafted seedlings will increase greatly after grafting, resulting in a decrease in the survival rate of grafting. reduce
