Tomato cutting water planting rooting seedling-raising method

Abstract

The invention discloses a method for inhibiting growth and development of tomato side branches. The method comprises the following steps of performing exogenous coating to a tomato plant by adopting a Strigolactones solution with the concentration of 7.5-10.0umol*L-1; or performing exogenous injection to the tomato plant by adopting a Strigolactones solution with the concentration of 2.5-5.0umol*L-1; or soaking tomato seedling roots for 20-24 hours by adopting a Strigolactones solution with the concentration of 10-20.0umol*L-1 in 1-2 days before planting the seedlings. Exogenous coating and injection are executed at the leaf axilla of the tomato stem branch part, and the dosage thereof is 10uL / strain. According to the method, growth and development of tomato side branches can be obviously inhibited, labor consumption, and disease and pest spread are reduced, thereby improving plant growth and yield and quality; the method is simple in operation and pollution-free, and is applied to cultivation of an open field tomato and a greenhouse tomato.

Description

technical field [0001] The invention relates to a seedling raising method, in particular to a seedling raising method for tomato hydroponic cutting rooting through nutrient solution, and belongs to the technical field of vegetable cultivation. Background technique [0002] China is the country with the largest facility area in the world. In 2014, the area of ​​facility vegetables reached more than 57 million mu, which has become an important guarantee for promoting farmers' income and social and economic growth. tomato( Solanum lycopersicum L.) is favored by consumers for its bright color and rich nutrition, and has become one of the main vegetable crops cultivated in facilities. At present, my country's tomato production is mainly based on sowing seedlings. In recent years, the cost of tomato seeds has been increasing day by day. The main reasons are: (1) Most of the cultivated tomatoes on the market are hybrids, which cannot be saved, and a large amount of money needs t...

Problems solved by technology

In the prior art, most of the cutting methods that have been applied are substrate cutting and soil cutting. Due to factors such as differences in medium characteristics, external nutritional status, and unbalanced water management, the rooting rate is low, the number of roots is small, the growth is inconsistent, and the survival rate is unstable. and other issues have affected the promotion and application of tomato cutting seedlings
