Abstract
The invention discloses a cassava cultivation technique, and belongs to the field of planting. The cassava cultivation technique comprises the steps of soil preparation, seed stem selection and cutting, field planting and field management. According to the step of soil preparation, furrowing and planting are carried out according to spacing in the rows and spacing between the rows, soil ploughing depth is 30 cm to 40 cm, furrowing depth is 20 cm to 25 cm, the spacing in the rows and spacing between the rows is 0.8*0.8 m or 0.9*0.9 m or 0.8*1.0 m, and 800 to 1000 plants are planted per mu. According to the step of seed stem selection and cutting, the middle and lower stems of main stems which are fully ripe, thick in stem, dense in joint, perfect in bud point, fresh, free of damage, diseases and pests and have milk in cuts are selected as seed stems, and the selected seed stems are cut into stem sections of 10 cm to 15 cm in length by using sharp knives. By the adoption of the technological means, the yield of the cassava can be improved greatly, selection of fertilizer is simple, cost is lowered, and the survival rate of the cassava is improved at the same time.
Description
Technical field
The present invention relates to field of planting, especially a kind of cassava culture technique.
Background technology
Cassava.Another name is wooden sweet potato, and cassava, is listed as the large tuber crops in the world three with potato, Ipomoea batatas.Originate from tropical America, extensively cultivate in the torrid zone and part subtropical zone, horizontal distribution is between north and south latitude 30 is spent, and vertical distribution is at height above sea level below 2000 meters.The cassava cultivation history of existing nearly 5,000 years, approximately has 100 countries and regions plantation cassavas at present in the world.According to FAO (Food and Agriculture Organization of the United Nation) (FAO) statistics, within 2005, world's cassava total amount is 20836.4 ten thousand tons, and wherein African 11460.7 ten thousand tons account for 55%; 5634.6 ten thousand tons, Asia, accounts for 27% of world's total amount; Latin America is 3721.8 ten thousand tons, accounts for Gross World Product 17%; Oceania is 19.4 ten thousand tons.Cassava, to become main non-irrigated grain and the forage crop of extensive plantation, is the main heat energy source in the daily food in many tropical country.
How improving cassava production, solve world food problem in short supply, is the subject matter of present stage.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, provide the cultivation of a kind of cassava to squeeze technology, have cassava production, the feature with low cost of improving.
The technical solution used in the present invention is as follows: cassava culture technique, comprises step: kind of a stem, field planting, field management are cut in whole ground, choosing;
Described wholely for pressing seeding row spacing Furrow sowing, the dark 30-40cm of plough soil, dark 20-25cm ditches; Seeding row spacing adopts 0.8 * 0.8m, 0.9 * 0.9m or 0.8 * 1.0m, and mu is planted 800-1000 strain, the too much or very few output that all affects;
Described choosing cut kind of stem for choosing is fully aging, stem slubbing is close, bud select intact, fresh, do not damage, otch has milk, hypomere is made a kind stem in the stem of anosis worm, the kind stem of choosing is chopped to the long stem section of 10-15cm with scraper, needs that otch is level and smooth, crack-free, bud point remain intact; It is fast that it plants rear germination, emerges early and neat, and seedling is thick fast long, and output is high.
Such scheme is done further preferably, described definite value is on the good plot of plow harrow, by line-spacing, play furrow, apply base manure, furrow face covers upper mulch film, mulch film surrounding is real with earth press seal, then by spacing in the rows, cassava stem section is inserted in to furrow film both sides or on furrow film, beats duck eye and will plant stem insertion, and kind of a stem is exposed to furrow face 3-5cm.
Such scheme is done further preferably, and described field management comprises after-culture, thinning and fertilising;
Described after-culture is that cassava is planted rear 3-5 week, now often has a small amount of kind of stem due to of poor quality or plant uncomfortable the causing of rear subenvironment and be short of seedling, and after-culture on the position being short of seedling in time, to save seedling from damage;
Described thinning is for when the height of seedling 15-20cm, by the plant of many seedlings, and every young plant 1-2 seedling, all the other fall; After coming up, same stem often has a plurality of seedling to grow, as lets alone growth, causes between increase in density, plant and covers and nutrient consumption;
Described fertilising is executed seedling fertilizer for planting rear height of seedling 20cm, and mu is executed urea, each 10kg of potassium chloride, to urge growth of seedling, sturdy; Execute knot potato the 6-7 month fertile, mu is executed potassium chloride 15kg, to urge tying potato, increase potato number, promotes potato piece to expand.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows: adopt above-mentioned technological means can greatly improve the output of cassava, comparatively simple to choosing of fertilizer, reduced cost, the survival rate of cassava is also improved simultaneously.
