Problems solved by technology

However, the current technology also has the following defects: (1) The use of dwarf varieties for planting is restricted by varieties, and there are few dwarf varieties and poor selectivity; the use of plant-specific growth inhibitors is easy to cause pesticide residues and increase labor costs, especially Cassava is basically closed after mid-June, and it is not easy to spray in the field. (2) Due to land restrictions, there are relatively few leeward areas, which restricts the cassava planting area. (3) Planting windbreaks requires a long cycle and a large investment , only suitable for large-scale planting, not suitable for small-scale planting, (4) increase labor costs, and even cause a certain degree of production reduction

Embodiment 1

[0069] The wind-resistant and yield-increasing cultivation technique for cassava of the present invention has the following cultivation technique steps:

[0070] (1) Soil preparation and furrowing

[0071] Choose land that is not too barren, with little gravel, no water, sheltered from the wind, or protected by forest segments. Sow from early March to early April. Deep plow and rake the land 1-2 months before sowing. Good ridges, planting furrows and plant-to-row spacing, the plant-to-row spacing is 80cm×100cm, and the row spacing is one meter;

[0072] (2) Selection of seed stems

[0073] Select the middle and lower part of cassava stalks that are fully mature, thick and knotted, with intact bud points, fresh, undamaged, with milk in the incision, and free of pests and diseases as the seed stem, and cut flat with a knife. The length of the cut seed stem is 30cm;

[0074] (3) Girdling

[0075] Use a girdling knife to cut a width of 1-2 cm around the middle of the stem lengt...

Embodiment 2

[0094] The wind-resistant and yield-increasing cultivation technique for cassava of the present invention has the following cultivation technique steps:

[0095] (1) Soil preparation and furrowing

[0096] Choose land that is not too barren, with little gravel, no water, sheltered from the wind, or protected by forest segments. Sow from early March to early April. Deep plow and rake the land 1-2 months before sowing. Good ridges, planting furrows and plant-to-row spacing, the plant-to-row spacing is 60-70cm×120-150cm, and the row spacing is one meter;

[0097] (2) Selection of seed stems

[0098] Select the middle and lower part of cassava stalks that are fully mature, thick and knotted, with intact bud points, fresh, undamaged, milky in the cut, and free of pests and diseases as the seed stems, and cut flat with a knife. The length of the cut seed stems is 32cm;

[0099] (3) Girdling

Embodiment 3

[0119] The wind-resistant and yield-increasing cultivation technique for cassava of the present invention has the following cultivation technique steps:

[0120] (1) Soil preparation and furrowing

[0121] Choose land that is not too barren, with little gravel, no water, sheltered from the wind, or protected by forest segments. Sow from early March to early April. Deep plow and rake the land 1-2 months before sowing. Good ridges, planting furrows and plant-to-row spacing, the plant-to-row spacing is 55-70cm×120-150cm, and the row spacing is one meter;

[0122] (2) Selection of seed stems

[0123] Select the middle and lower part of cassava stalks that are fully mature, thick and knotted, with intact bud points, fresh, undamaged, with milk in the incision, and free of pests and diseases as the seed stem, and cut flat with a knife. The length of the cut seed stem is 33cm;

Abstract

The invention belongs to the technical field of crop cultivation, and particularly relates to a wind-resisting and yield-increasing cassava cultivation technology. The technology comprises the following technical steps of land preparation, furrowing, selection of seed stems, girdling, fertilizing at the two ends of the seed stems, weeding, covering of a mulching film, retention of seedlings on both sides, spraying, fertilizing and chopping of stems at the two ends. By adopting the wind-resisting and yield-increasing cassava cultivation technology, the problems of small rotting quantity of the seed stems, unbalanced rooting, low yield and poor wind resistance in the conventional cassava planting method are solved. The wind-resisting and yield-increasing cassava cultivation technology has the characteristics of increasing the rooting quantity of cassava seed stems, uniform rooting distribution, balanced distribution of cassava around the seed stems, large quantity of cassava, high yield, high wind resistance, easiness in operation and practicability.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and relates to a cassava cultivation technology, in particular to a cassava wind-resistant cultivation technology. Background technique [0002] Cassava (Manihot Esculenta Crantz) is one of the three largest tuber crops in the world and one of the seven major crops with a global output exceeding 100 million tons. Cassava has the reputation of "king of starch", "underground granary" and "special crop". The comprehensive utilization value is very high, and its roots, stems and leaves can be used. It is the most important root food, chemical raw materials and biomass energy crops in tropical regions. Cassava can be processed to produce more than 2,000 varieties of products in five series, including starch sugar, starch, alcohol, organic chemicals, and fine chemicals, which can be widely used in food, medicine, alcohol, textiles, papermaking, sugar and coatings And so on in various industri...
