Problems solved by technology

[0003] However, in the cultivation technology of potato planting under film mulching, setting seedlings is a time-intensive, labor-intensive and time-consuming key link, which can only be done manually. With the continuous expansion of potato planting area and rising labor costs, field Seedling setting operation has become an important problem that affects and troubles the expansion of potato production

Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the examples. The examples are only illustrations of the present invention, not limitations of the present invention.

[0015] The method for cultivating potato seedlings on a half-high ridge covered with film and self-rupturing, the steps are as follows:

[0016] Land plot selection: choose sandy loam or loam soil with flat terrain and deep soil layer, and the plots are concentrated to facilitate mechanized operations. Cereal crops, beans, radishes, Chinese cabbage, etc. should be used as the previous crops, rather than solanaceous crops, in order to avoid serious pests and diseases.

[0017] Soil preparation and fertilization: Deep plowing is carried out in winter, and the plowing depth is preferably 25-30cm. It is also possible to perform deep plowing before sowing, and use a rotary tiller to sow after rotary tillage; where irrigation conditions are available, it can be combined with autumn ...

Abstract

The invention discloses a half-height ridge mulching and self-germination type potato cultivation method includes: carrying out drip irrigation under half-height ridge mulches, and sowing on ridges according to a double-row planting mode with a small line spacing being 30-35cm and a large line spacing being 55-60cm, wherein the row spacing is 32-38cm, and the sowing density is 52500-60000 plants / hm<2>; laying irrigation pipes among small-line-spacing areas; sowing in early May as long as the temperature of earth 10cm in depth reaches 8-10 DEG C, wherein sowing depth is 6-12cm, ridging height is 10cm, ridge width is 50-65cm, ridge distance is 100-130cm, thickness of covering soil is 5-7cm, and earthing is supposed to be carried out on the same day of sowing or finished within 5-7d. By compete earthing after sowing, soil fertilizer conditions are effectively improved, the mulches are protected from being broken by strong wind in spring, and growth of grass on land is restrained. In addition, the method has the advantages of earth temperature raise, shortening of germinating and harvesting time and realization of self-unearthing of the potatoes.

Description

technical field [0001] The invention relates to a potato cultivation method, in particular to a potato half-high ridge film-covered self-breaking film seedling cultivation method. Background technique [0002] Potato is the main economic and food crop in our country. It likes cold and cold, is resistant to barrenness, and has wide adaptability. It needs a lot of water during the growth process, especially in the growth period of potato tubers. The water requirement is even stricter. For the northern dry-farming areas where the climate is dry and rainless, the spring is more windy and sandy, and the water erosion and wind erosion are serious, meeting the water requirements of different growth stages of potatoes is a key problem in its growth. Traditional potato cultivation methods can no longer meet the needs of market development. Over the years, the agricultural scientific research department has absorbed advanced cultivation methods at home and abroad, and adopted the tec...
