Problems solved by technology

[0003] At present, the sweet potato cultivation in my country mainly adopts the traditional modes of film mulching, greenhouse cultivation and open field cultivation. The cultivation process includes traditional operation methods such as site preparation and fertilization, seed selection and acceleration of germination, ditching and sowing, and mulching and covering soil. The disadvantages are: sweet potatoes are on the market Concentration, resulting in price squeeze competition, short market supply period, easy to be affected by the weather during the cultivation and management process, which is not conducive to grasping the market situation, once a drought occurs, it will cause diseases and insect pests, reduce production, and the effect of increasing production and income is unstable

Embodiment Construction

[0014] 1. Land preparation and ridge: Choose convenient drainage and irrigation, loamy or medium loamy land, fertilize the land, can apply fully decomposed biogas residue fertilizer, chicken manure, pig manure or other organic fertilizers of more than 4000 kg / mu, high-quality potassium sulfate The compound fertilizer is more than 50-75 kg / mu, and then make a furrow, which is calculated as 12 meters wide from east to west and 55 meters long from north to south. In the greenhouse, 5 middle-arch shed furrows are reserved in the north-south direction, with a width of 1.76 meters per piece and a width of 20 meters. About one centimeter, the depth of the furrow is about 15 centimeters, according to the amount of fertilizer applied in the above unit, the base fertilizer is applied in advance, and each furrow has 3 ridges, the width of the ridge is about 50 cm, the height is 15 cm, and the width of the furrow is about 10 cm. When sowing, the innermost layer of film is covered with weed...

Abstract

The invention provides a novel green house pachyrhizus efficient culture technology, which is characterized by comprising five steps including land preparation and ridge forming, seeding at proper time, early stage management, middle stage management, back stage management and harvesting. The biological characteristic of cold resistance of pachyrhizus is utilized, the heat insulation effects of a vinyl house and a middle-arch shed are used, the auxiliary measures of middle-arch shed addition and plastic mulching are adopted, and the technology solves the problem that during the planting relying on the traditional planting mode, the whole-year production of pachyrhizuses cannot be realized, or higher output is not accompanied by a higher income although the whole-year production of the pachyrhizuses is realized. The novel green house pachyrhizus efficient culture technology is applicable to the field of vegetable planting.

Description

[0001] technical field [0002] The invention relates to the field of vegetable planting, in particular to a new technology for high-efficiency cultivation of sweet potatoes in greenhouses. Background technique [0003] At present, the sweet potato cultivation in my country mainly adopts the traditional modes of film mulching, greenhouse cultivation and open field cultivation. The cultivation process includes traditional operation methods such as site preparation and fertilization, seed selection and acceleration of germination, ditching and sowing, and mulching and covering soil. The disadvantages are: sweet potatoes are on the market Concentration leads to price squeeze competition, short market supply period, and the cultivation and management process is easily affected by the weather, which is not conducive to grabbing the market. Once a drought occurs, it will cause diseases and insect pests, reduce production, and the effect of increasing production and income is unstab...
