The invention discloses a
greenhouse cultivation method of tomatoes, which consists of the following steps of 1, selection of varieties: tolerant varieties with the advantages of
cold resistance, shade resistance, fast growth, less leaves and high
photosynthetic capacity in spring are selected; 2, seeding in optimum period: the growth period of tomatoes growing in a
greenhouse is longer than that of tomatoes growing in
open field from seeding to harvesting; 3, autumn and winter cultivation:
greenhouse cultivation tomatoes which come into the market before and after Spring Festival are cultivated; 4,
overwintering cultivation: the seeding date is generally at the beginning of September; and 5, winter and spring cultivation:
greenhouse cultivation is carried out on tomatoes which are harvested in spring. Seedlings are completely raised in a greenhouse or a
hotbed in a freezing season, if the temperature condition of the greenhouse is good, and the average temperature in the
daytime can be enabled to be about 25 DEG C, sparse seeding can be generally carried out,
seedling separating is not needed, proper
bacteria thinning out is performed, the
seedling stage is 30-40 days, and early planting is performed when six to seven main leaves grow out; and if the seedlings are seeded in the
hotbed,
seedling separating can be carried out for saving protecting equipment, and the seedling stage is prolonged to 70-80 days, so that early harvesting in spring can be ensured, and grow seedlings can be flexibly seeded in various regions. The method has the advantages that the plants grow in order, the yield is increased, and the plants are not easily infected with diseases, the grade of commodities is improved,
disease prevention and continuous appearing on the market of products are favored, labor
wasting and time
wasting and premature senility of the tomatoes are avoided, and accordingly the economic benefit is improved.
