Tomato lateral branch cutting fast breeding method

Abstract

The invention belongs to the technical field of plant cultivation, and particularly relates to a tomato lateral branch cutting fast breeding method which includes the steps: taking lateral branches divided from the upper portion of a second spike insertion section in the middle of a tomato main stem as cuttings with the length of 10cm-15cm; rapidly beveling bases of the selected lateral branches by a disinfected blade and retaining fixed buds and 3-4 compound leaves; cutting cut cuttings into mixed solution of nutrient solution and growth regulating agents, cultivating the cuttings until root systems grow well, and then transplanting seedlings. The volume ratio of the nutrient solution to the growth regulating agents in the mixed solution is 1:1. The mixed solution of the nutrient solution and the growth regulating agents is used for raising the seedlings by cutting, the seedlings can be directly germinated and transplanted, seedling growth speed is high, manual operations such as weeding and watering are omitted, and the method has the advantages of low cost, capabilities of saving time and labor and the like.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a method for rapid propagation of side branch cuttings of tomato. Background technique [0002] China is the country with the largest area of ​​protected vegetables in the world. In 2014, the area of ​​protected vegetables reached 3.86 million km 2 , Has become an important guarantee to promote farmers' income and social and economic growth. Tomato is one of the main vegetable crops cultivated in facilities. It is favored by consumers because of its bright color and rich nutrition. [0003] Tomato, that is, tomato (scientific name: Lycopersicon esculentum Mill.), is an annual or perennial herbaceous plant of the genus Tomato in the family Solanaceae. Inflorescence peduncle 2-5 cm long, often 3-7 flowers, calyx radial, corolla radial, berry oblate or nearly spherical, fleshy and juicy, yellow seed, flower and fruit period in summer and autumn. At present, my country's...

AI Technical Summary

Problems solved by technology

At present, my country's tomato production is mainly based on sowing seedlings, but the cost of tomato seeds is increasing day by day, and the seedling time is longer

In recent years, cutting seedlings have become an effective means to shorten the seedling cycle and reduce production costs in facility tomato production. However, the currently used substrate cuttings and soil cuttings are mainly affected by factors such as substrate or soil physical and chemical properties, nutritional status, and water management. Problems such as low survival rate, small number of new roots, and inconsistent growth have seriously affected the promotion and application of tomato cutting seedlings
