Efficient method for cultivating flue-cured tobacco seedlings, summer cucumbers and autumn delayed cowpeas in one year

Abstract

The invention discloses an efficient method for cultivating flue-cured tobacco seedlings, summer cucumbers and autumn delayed cowpeas in one year. The crop rotation period is reasonably arranged, and the flue-cured tobacco is sown from the middle ten days of January to the middle ten days of February, and the flue-cured tobacco is harvested from a greenhouse from the last ten days of April to the middle ten days of May; the summer cucumbers are sown and raised in the last ten days of April, planted in the flue-cured tobacco greenhouse in the middle ten days of May, and harvested from the end of June to the middle ten days of August; the autumn delayed cowpeas are planted in a cucumber compartment from the first ten days of July to the middle ten days of July before the cucumbers are completely harvested, and the autumn delayed cowpeas are harvested and sold on the market from the first ten days of September to the middle and last ten days of October. Two types of out-of-season vegetables are planted after the tobacco seedlings are harvested from the flue-cured tobacco greenhouse, appropriate vegetable varieties and fine varieties are selected, three kinds of crops are efficiently cultivated in the flue-cured tobacco greenhouse in one year, the utilization rate of the flue-cured tobacco greenhouse facility and land is increased, the cropping index and the comprehensive yield of the greenhouse are increased, the income of cucumbers and cowpea vegetables is added to the net income of tobacco growers, the problem that the flue-cured tobacco greenhouse is left unused for a long time after the flue-cured tobacco seedlings are harvested from the greenhouse is solved, and economic benefits and social benefits are very obvious.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a high-efficiency cultivation method for growing flue-cured tobacco seedlings, summer cucumbers, and autumn-late late cowpea three crops a year in a flue-cured tobacco seedling cultivation shed. Background technique [0002] China's flue-cured tobacco production areas are developing rapidly in southwest regions such as Yunnan, Guizhou, and Sichuan. At present, the scale of tobacco leaves in Guizhou Province is the second largest in the country, and its production and sales of tobacco leaves account for about 15% of the country's total. It has become a major province of tobacco leaf production in my country. At present, there are about 3 million square meters of flue-cured tobacco seedling greenhouses in the province. In order to meet the supply of seedlings for the tobacco leaf bases in the province, the five-year plan will reach 6 million square meters. However...
