Description

Planting method for improving yield and quality of cassava
Technical Field
The invention belongs to the technical field of crop planting, and particularly relates to a planting method for improving the yield and quality of cassava.
Background
Cassava (the scientific name: Manihot esculenta Crantz) is a plant of the genus Manihot of the family Euphorbiaceae, is drought-resistant and barren-resistant, is widely planted in more than 100 countries or regions such as Africa, America and Asia, is one of three potato crops, is the third food crop in a hot zone, is the sixth food crop in the world, is called the king of starch, and is the grain for nearly six hundred million people in the world. Cassava has the characteristics that other crops cannot meet the requirements, such as high utilization rate of climate resources, strong photosynthesis capability and highest production level of biological energy; barren resistance, drought resistance and wide adaptability, and can also be interplanted and mixed with other crops; the starch content is high, and the ratio of starch in the root tuber is as high as 30-35%. Cassava is also an important energy type substance in many countries in tropical and subtropical regions. The cassava can be used as grain, feed, energy and industrial raw materials. Cassava is listed as one of the main raw materials for producing fuel ethanol in the future in China. With the increase of the demand of cassava, the cassava planting area can continue to expand year by year.
The cassava has edible and industrial cassava, and the edible cassava has health care functions of treating swelling and sore and ulcer, resisting and preventing cancer, diabetes and hypertension, treating cystitis, protecting liver, resisting oxidation and the like. In addition, the potato tuber contains rich nutritional factors and anti-nutritional factors, wherein the main anti-nutritional factors comprise tannin, and the tannin anti-nutritional factors in cassava can influence the nutritional digestibility of a human body. Therefore, it is necessary to research and develop a planting method for improving the yield and quality of cassava and improving the nutrient absorption of cassava roots by human bodies.
Disclosure of Invention
The invention aims to solve the technical problems and provides a planting method for improving the yield and quality of cassava, and the method can solve the technical problem of high tannin content of fresh cassava roots.
The technical scheme of the invention is as follows:
a planting method for improving the yield and quality of cassava comprises the following preparation steps:
(3) ridging: ridge width is 0.9-1.2m, furrow width is 0.7-0.9m, and ridge height is 0.2-0.3 m;
(4) applying a base fertilizer: per hm2Applying organic fertilizer for 1.2-2 t;
(3) seed soaking: putting cassava seed into the seed soaking liquid, and soaking for 15-30min at room temperature;
(4) sowing: sowing the soaked cassava seeds on the ridge surface in a single row;
(5) field management: weeding in time, reserving 1-2 seedlings in each hole, sowing for 4-5 months, topdressing every hm2300 kg of compound fertilizer is applied, and the compound fertilizer is applied to the middle of the ridge surface;
(6) harvesting seed stems: selecting seed stems of the hybrid seeds, cutting, bundling and storing;
(7) and (4) harvesting root tubers: and (4) harvesting by using a machine.
The seed soaking liquid is prepared from honeysuckle and cablin potchouli herb, and the preparation method of the seed soaking liquid comprises the following steps: mixing flos Lonicerae and herba Agastaches, pulverizing, adding water 23-28 times of their total weight, boiling, decocting with slow fire for 30-45min, and cooling. Wherein the flos Lonicerae is flower bud of Lonicera japonica Thunb of Caprifoliaceae. Harvesting before blooming in summer, removing impurities, and drying to obtain the final product containing luteolin, inositol 1%, volatile oil, terpenes, phenolic acid, etc. Aerial parts of Pogostemon cablin (Blanco) Benth, a plant of the family Pogostemon cablin (Agastache rugosa) Labiatae. Collecting aerial parts when branches and leaves are flourishing, sun drying and stewing, and repeating to dry. The volatile oil mainly contains patchouli alcohol and patchouli ketone. The seed potatoes are soaked in the seed soaking liquid, so that the quality of the seed potatoes can be enhanced, and the quality and the yield of the produced cassava are improved.
The ridge height of the invention is 0.25m, and the interval between two ridges is 0.75 m. The ridge height and the intervals are set, so that cassava can be harvested conveniently, the cassava bright potato rate is improved, and the damage of the cassava is reduced.
