A kind of method of tomato cultivation

Abstract

The invention relates to a tomato plant culturing method. The tomato plant culturing method comprises the step that tomato plants in the seedling stage of the second stage are irrigated in a drop irrigation mode under the culturing conditions, wherein according to the culturing conditions, the temperature at daytime ranges from 10 DEG C to 12 DEG C, the temperature at night ranges from 5 DEG C to 8 DEG C, the light intensity ranges from 150 umol.m<-2>.s<-1> to 250 umol.m<-2>.s<-1>, the light period is 7-9 h / 15-17 h, and the humidity ranges from 80% to 90%; according to the irrigation mode, a pimacol solution with the concentration of 12-14 mg.L<-1> is used for carrying out drop irrigation, drop irrigation is carried out every 6-8 days, the irrigation amount for each tomato plant in the seedling stage of the second stage each time ranges from 80 mL to 120 mL, and the seedling stage of the second stage refers to the period from spreading of two to three true leaves to emerging of large flower buds. By means of the tomato plant culturing method, the time span of the tomato plant fruiting period under the low temperature and the lower light level can be obviously prolonged.

Description

technical field [0001] The invention relates to a tomato cultivation method. Background technique [0002] In the solar greenhouse in northern my country, the growth of tomato has long been subjected to low temperature and low light environment (10 / 5±2℃, 150±30μmol·m -2 ·s -1 ), resulting in abnormal development of tomato, shortened growth cycle, and more susceptible to disease in the coldest month. Specifically, low temperature and low light can reduce the expression of plant N-transport protein genes, thereby reducing the activity of nitrogen metabolism-related enzymes and nitrogen content, plant photosynthesis, mineral element content and ATPase activity, and it will also seriously affect the tomato plant. Hormone levels seriously affect the normal growth and development of plants, and even lead to tomato growth cycle disorder, abnormal development, and short fruiting period. [0003] Therefore, there is an urgent need for a cultivation method that can prolong the time...

Specifically, low temperature and low light can reduce the expression of plant N-transport protein genes, thereby reducing the activity of nitrogen metabolism-related enzymes and nitrogen content, plant photosynthesis, mineral element content and ATPase activity, and it will also seriously affect the tomato plant. Hormone levels, which seriously affect the normal growth and development of plants, and even lead to tomato growth cycle disorder, deformed development, short fruiting period, etc.
