Description

A kind of Ipomoea batatas efficient cultivation method

Technical field

The invention belongs to agricultural cultivation field, be specifically related to a kind of Ipomoea batatas efficient cultivation method.

Background technology

Ipomoea batatas, has another name called sweet potato, pachyrhizus, sweet potato etc., is rich in protein, starch, pectin, cellulose, amino acid, vitamin and several mineral materials, has the reputation of " life prolonging food ".There is the effect such as anticancer, cardioprotection, prevention pulmonary emphysema, diabetes, fat-reducing.

Ipomoea batatas is a kind of high yield and adaptable cereal crops, with industrial and agricultural production and people's lives in close relations.Block is eradicated and is done outside staple food grain, and be also the important source material of food processing, starch and alcohol process industry, root, stem, leaf are again excellent feeds.

For these years, easily plant due to these thing from abroad and be easy to get, price is cheap, and people have faded from memory it gradually in the preciousness of foreign country and the risk of introducing a fine variety, and only treat as coarse food grain and feed.In fact, Ipomoea batatas has high nutritive value.Be described as life prolonging food in Japan, there is again good medicinal efficacy simultaneously.

Substrate culture Ipomoea batatas refers to and replaces soil by matrix, by Ipomoea batatas field planting in matrix, in process of production by the method for drip irrigation or trickle irrigation to Ipomoea batatas supply moisture and nutrient solution.Its technology of substrate culture Ipomoea batatas is the simplest, effect is best, is a kind of mode the most easily promoted in pattern in current soilless culture.Because medicinal effects is obvious, consumption is increasing, and the natural resources amount of Ipomoea batatas is very limited, causes Ipomoea batatas can not satisfy the demands far away, and in addition by the impact of natural climate condition, quality and quantity are all difficult to ensure.What the approach overcome the above problems adopted usually is that Ipomoea batatas is carried out artificial cultivation, but owing to lacking standardized planting (GAP) technology of Ipomoea batatas, make Ipomoea batatas planting scale little, planting cost is high, and quality is unstable.

Summary of the invention

The invention provides a kind of Ipomoea batatas efficient cultivation method, it is characterized in that, described method comprises the steps:

(1) build cultivation bed: on the plot of sterilization, build the cultivation bed that length and width degree is about 1.3-1.5m, build the edge of bed of high about 22-23cm in surrounding, stay the aisle of 50-55cm between adjacent, spread layer of plastic film inside;

(2) culture matrix processed: first diluted by sucrose with water, dissolves, wheat straw, chicken manure, pond sludge is mixed and stirred, is more again mixed with the water of bacterium liquid 60-70% with production by mixed material, fermentation medium;

(3) medium is executed: the production medium fermented paving is imposed on plastic film in cultivation bed, and medium discharges thickness and is about 25-30cm;

(4) nutrient solution is prepared: get 95% alcohol 10 kg and sucrose 1 kg mixed dissolution, make sucrose liquid stand-by, 1-2h before enforcement sprays, vinegar 0.5 kg is blended in sucrose nutrient solution barrel, tighten cover and rock Homogeneous phase mixing, get sucrose nutrient solution stoste in 1:100 ratio and be blended into clear water;

(5) seedling is selected: select that seedling age is 24-27 days, Ipomoea batatas seedling without damage by disease and insect, robust plant;

(6) furrow are played: whole good ground is made the furrow of furrow face width 85-95cm, high 20 cm in furrow face, furrow width 35 cm, ditch depth 30 cm, and furrow length is determined according to landform, and surrounding holds drain ditch successfully;

(7) plant: when Ipomoea batatas seedling grows to 5-6 sheet true leaf, select to transplant overcast and rainy, every cave kind 1 young plant, line-spacing is 35-45 cm, and spacing in the rows is 35 cm, every mu of plantation 4000-5000 strain;

(8) nutrient solution is discharged: according to each vegetative stage demand supplies and nutrient solution of Ipomoea batatas seedling plant, each mu executes nutrient solution 40-50L;

(9) intertill and clean tillage: to Ipomoea batatas Feng Hanghou, is shown in that grass just removes, and keeps field without weeds.

The beneficial effect of the invention:

Compared with prior art, matrix quality of the present invention is loosened, be rich in organic matter, be conducive to the growth of Ipomoea batatas, Ipomoea batatas growth is swift and violent, and quality safety, effective, stable, controlled, the establishing in large scale that can standardize, plantation small investment, production cost are low, high efficiency, can be used as the strategic industry in the strong county of leading industry He Qiang city of peasant programme, have considerable economic benefit.
