Problems solved by technology

Plastic film mulching cultivation technology can effectively improve the yield and quality of potatoes, but ordinary plastic film cannot be recycled and is difficult to degrade, so it accumulates in the soil year by year, causing serious impact on the agricultural ecological environment
After the potatoes are sown, it is necessary to manually cover each ridge with film, press the soil on the film surface, and then carry out large-scale soil cultivation on the film surface to ensure that the film on the ridge surface is completely covered. During the potato harvest period, it is necessary to manually remove the film first, which is time-consuming and laborious. It is beneficial to the large-scale planting and mechanized harvesting of potatoes, and the production efficiency is very low

Embodiment 1

[0027] (1) Land selection and land preparation: Select fields with sufficient water sources, convenient irrigation, and rice as the previous crop, which can not only make full use of mineral elements and nutrients in the soil, but also can significantly reduce the occurrence of potato diseases and insect pests, and rice harvest Afterwards, fertilization: use chicken manure organic fertilizer 600kg, compound fertilizer 120kg; This compound fertilizer selects Sumisho compound fertilizer (16:8:18), wherein contains N ≥ 16% in the compound fertilizer, P 2 o 5 ≥8%, K 2 O≥18%.

[0028] (2) Ridging, the width of the ridge surface is 80cm, the width of the ridge bottom is 100cm, the height of the ridge is 15cm, and the width of the ditch is 20cm, so as to ensure that the soil in the plow layer is finely divided and flat, and at the same time clean the root stubble on the ridge surface so as not to affect the quality of the film, otherwise it will biodegrade The weeding film cannot s...

Embodiment 2

[0035] (1) Site selection and site preparation: select the loose sandy loam field with sufficient water source and convenient irrigation, the previous crop is potato, fertilization: use chicken manure organic fertilizer 700kg, compound fertilizer 130kg; this compound fertilizer selects Sumisho compound fertilizer (16: 8:18), wherein the compound fertilizer contains N≥16%, P 2 o 5 ≥8%, K 2 O≥18%.

[0036] (2) Ridging, the width of the ridge surface is 80cm, the width of the ridge bottom is 100cm, the height of the ridge is 15cm, and the width of the ditch is 20cm, so as to ensure that the soil of the plow layer is finely divided and smooth, and at the same time, the root stubble on the surface of the ridge is cleaned so as not to affect the quality of the film covering;

[0037] (3) Sowing: sowing in the shape of "product" along the ridge surface successively, the sowing depth is 5cm, the bud eyes are facing down, the wound is facing up, the row spacing in the ridge is 20cm, ...

Abstract

The invention provides a film mulching cultivation method for potatoes. The film mulching cultivation method is characterized by including the following steps: (1) selecting and fertilizing a field, and performing soil preparation and ridging; (2) performing sowing; (3) simultaneously coating every two adjacent ridges by biodegradable weeding mulching films which are tightly attached to the corresponding ridge surfaces, and performing earthing-up between every two adjacent ridges by an earthing-up machine; (4), performing field management and harvesting. The film mulching cultivation method integrates film mulching with film-surface soil compaction and film-surface earthing-up, the planting process of the potatoes is simplified, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a film-mulching cultivation method for potatoes. Background technique [0002] Potatoes have become the fourth largest food crop after rice, wheat and corn. However, the average yield of potatoes in my country is low, far from the average yield of some developed countries in Europe and the United States such as the Netherlands, and the potential for increasing production is huge. Plastic film mulching cultivation technology can effectively improve the yield and quality of potatoes, but ordinary plastic film cannot be recycled and is difficult to degrade, and accumulates in the soil year by year, causing serious impact on the agricultural ecological environment. After the potatoes are sown, it is necessary to manually cover each ridge with film, press the soil on the film surface, and then carry out large-scale soil cultivation on the film surface to ensure that the film on ...
