Multiple-cropping method of early-mature potato, celery and leafy vegetables in arched shed

Abstract

The invention relates to a multiple-cropping method of early-mature potato, celery and leafy vegetables. The multiple-cropping method comprises the following steps: step 1, establishing the arched shed at an appropriate time; step 2, sprouting and seeding potatoes; step 3, applying base fertilizer to the potatoes; step 4, regulating temperature and humidity in the arched shed, and applying the fertilizer; step 5, nursing the celery; step 6, preventing early and late diseases of the potatoes; step 7, harvesting the potatoes and carrying out the land preparation and fertilization; step 8, planting the celery; step 9, carrying out the fertilizer and water management for the celery; step 10, applying the fertilizer to the celery, and carrying out the intertillage weeding; step 11, harvesting the celery; step 12, seeding the leafy vegetable; step 13, carrying out the field management for the leafy vegetable; step 14, harvesting the leafy vegetable. By utilizing the facility arched shed, the early-mature potatoes, celery and other leafy vegetables are produced according to respective production seasons, so that the multiple-cropping index of the land can reach 250 percent, the utilization rate of the land and light energy is increased, and the yield of the crops per unit area on the limited land area can be increased.

Description

Technical field: [0001] The invention relates to the technical field of crop multiple cropping, in particular to a method for multiple cropping of early-maturing potatoes, celery and leafy vegetables in an arch shed. Background technique: [0002] Potatoes are both grain and vegetable crops. As vegetables, in temperate semi-arid climate regions such as Northwest, Southwest, and Northeast my country, they are generally listed in large quantities in early October, and in June and July each year, the potatoes in the second cropping area have ended, and the first cropping District potatoes have not yet been listed in the gap period. Celery is a cold and cool vegetable. The peak sales period is from August to October. In southern my country, the high temperature season is from June to September every year. Celery cannot be produced. It is the blank period of southern celery. Guangzhou, Fujian, Hunan, Shanghai There is a great demand for celery in other places, and the contradictio...

Problems solved by technology

The superior climate characteristics and agricultural facilities are not fully utilized. The fundamental reason is the lack of advanced technical support and the inability to scientifically combine crop growth characteristics with local climate characteristics, agricultural facilities, and supply and demand markets.
