Spring Chinese cabbage, summer-autumn eggplant and autumn-winter asparagus lettuce three-season-in-one-year anti-season vegetable efficient cultivation method

Abstract

The invention discloses a spring Chinese cabbage, summer-autumn eggplant and autumn-winter asparagus lettuce three-season-in-one-year anti-season vegetable efficient cultivation method. In a gap date, first-season spring Chinese cabbages are sown in advance from the first ten-day period of February to the beginning of March, a setting date ranges from the first ten-day period of March to the beginning of April, and the first-season spring Chinese cabbages come into the market from the end of April to the middle ten-day period of May. Second-season summer-autumn eggplants are sown from the last ten-day period of March to the end of March, a setting date ranges from the last ten-day period of May to the end of May, and the second-season summer-autumn eggplants are harvested from the last ten-day period of July to the last ten-day period of September. Third-season autumn-winter asparagus lettuces are sown from the end of August to the first ten-day period of September, a setting date ranges from the end of September to the first ten-day period of October, and third-season autumn-winter asparagus lettuces are harvested from the last ten-day period of December to the beginning of January. Due to the fact that bolting-resistant varieties and the gap date are scientifically selected, a sowing data, the setting data and a seedling cultivation mode are improved, the early bolting problem of the spring Chinese cabbages is solved, three kinds of vegetables can come into the market in a slack season in one year in an anti-season mode, the demands of consumers are met, and the economic benefit is very remarkable.

Description

technical field [0001] The invention relates to the field of agricultural science and technology planting, in particular to a method for efficiently cultivating spring Chinese cabbage→summer and autumn eggplant→autumn and winter lettuce. Background technique [0002] In the prior art, there are many production and cultivation modes for three seasons a year, such as the annual production and cultivation mode of "spring bean→summer and autumn eggplant→winter lettuce" in Wuhan. Xining hybrid No. 2, Tianmajia bean, Lvlongjia bean, etc., were sown in early and mid-February, planted from the end of February to early March, harvested from the end of April to May, and closed at the end of May; Zilong 3 was used for autumn eggplant , Korean black longevity eggplant and other varieties, sow seedlings in mid-May, plant in mid-to-late June, harvest and market in early August, stop in early October, plant 2000 plants per mu, 80cm wide row, 40cm narrow row, and 50cm spacing between plants...

AI Technical Summary

Problems solved by technology

[0004] However, most of Sandu County and Luodian County in Guizhou Province are poverty-stricken and minority-inhabited areas, with many people and little land. For a long time, the traditional planting mode of dryland agriculture in these areas is "wheat → corn", "early beans, melons → Corn", "corn→autumn winter melon, beans" and other double-cropping systems in a year, the output value per mu can only reach 1520-5790 yuan, and the economic benefits are low. How to improve the land utilization rate in such areas, increase the multiple cropping index, adjust Agricultural planting structure, promoting farmers' income, and making the planted varieties meet market demand have become the subject of continuous exploration by agricultural scientists in Guizhou
