High-efficiency cultivation methods for flue-cured tobacco seedlings, summer Chinese cabbage, and autumn lettuce in three seasons a year

Abstract

The invention discloses an efficient cultivation method in three quarters of a year of flue-cured tobacco nurturing seedlings, summer Chinese cabbages and fall lettuces. Stubbles periods are arranged reasonably according to the following steps: in the first season, flue-cured tobacco nurturing seedlings is conducted, sowing of the flue-cured tobaccos is conducted from the middle of January to the middle of February, and all the flue-cured tobacco seedlings are out of a shed from late April to the middle of May; in the second season, the sowing and seeding of the summer Chinese cabbages are conducted form late April to the beginning of May, planting is conducted from late May to the beginning of June, and harvesting is conducted from the end of June to the end of July; in the third season, sowing of the fall lettuces is conducted from early July to the middle of July, planting is conducted from early August to the middle of August, harvesting and listing are conducted from the middle of October to late November. When the flue-cured tobacco seedlings are out of the shed, the idle flue-cured tobacco shed can be used for cultivating out-of-season vegetables which can be cultivated in two seasons, due to the fact that suitable good strains are selected and used, utilization rate of the flue-cured tobacco shed is improved, production value is increased, market requirement is met, economic benefit is also increased and rural incomes are raised.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a three-season high-efficiency cultivation method for growing flue-cured tobacco seedlings, Chinese cabbage in summer and lettuce in autumn in a greenhouse for growing flue-cured tobacco seedlings. Background technique [0002] Guizhou is one of the main production areas of flue-cured tobacco in the country. Flue-cured tobacco is a characteristic and advantageous industry in Guizhou, with an annual cultivation area of ​​2.5 million mu. With the vigorous advancement of modern tobacco agriculture, the level of large-scale production represented by intensive, specialized, and commercial flue-cured tobacco seedlings has been continuously improved, making flue-cured tobacco seedling greenhouses more and more concentrated. At present, there are 2.82 million square meters (4,228 acres) of flue-cured tobacco seedling greenhouses in the province that have been built and u...

Problems solved by technology

With the rapid expansion of seedling greenhouses, the greenhouses are idle for a long time after transplanting flue-cured tobacco, which not only wastes land resources, but also requires a large amount of money for daily management and maintenance

As far as the current utilization of flue-cured tobacco seedling greenhouses is concerned, most of the greenhouses only grow flue-cured tobacco seedlings for one season a year, and the utilization rate is very low. Even a small number of greenhouses plant some tomatoes, peppers, cucumbers, cabbage, Watermelons, etc., but they are only cultivated for one season

Moreover, tomato and pepper belong to the family Solanaceae, and continuous cropping diseases will increase, which will have a certain impact on the quality of flue-cured tobacco seedlings

At the same time, if the flue-cured tobacco seedling greenhouse is left idle for a long time and no one manages it, the steel frame will rot faster, and the cost of using the greenhouse will also increase
