Description

A kind of new technique of Radix Ipomoeae high-yield culturing

Technical field

The present invention relates to proportion of crop planting field, specifically the new technique of a kind of Radix Ipomoeae high-yield culturing.

Background technology

Rich in vitamin in Radix Ipomoeae, protein, trace element, edibility fiber and solubility non-oxidation material, more importantly it is contained within the anthocyanidin that substantial amounts of effect is peculiar, medical value is higher, often edible then have the effect such as fat-reducing, body building anti-cancer, existing market demand is relatively big, now introduces the new technique of a kind of Radix Ipomoeae high yield.

Summary of the invention

The present invention solves the technical problem in traditional Radix Ipomoeae yield, invent the new technique of a kind of Radix Ipomoeae high-yield culturing.

The present invention solves above-mentioned technical problem, the technical scheme taked, the new technique of a kind of Radix Ipomoeae high-yield culturing, it is characterized in that and includes procedure below:

1, selection of land and whole. Select weeds light sand few, saline and alkaline, autumn fine flat field wholely, turn over every mu in conjunction with the autumn and execute straw 150-200 kilogram, high-quality farm manure 4000 kilograms, winter-spring season ploughs a kind of farm tools soil moisture conservation in time.

2, nursery. Seedbed is built and is adopted heated kang seedling method, seedbed area is generally with 6 square metres conveniently, position at hidding and sunny side, north orientation south is sat in seedbed, seed selection potato selects " 868 " Radix Ipomoeae of strange land high yield and high quality to make mother's kind, every mu of land for growing field crops needs 2 square metres of seedbeds to carry out nursery, must prepare 200 potato seeds, about 50 kilograms. Sowing before and after April 5, the potato seed chosen is erected on bed surface sandy soil, application rate is 25 kilograms every square metre, thickness of sowing is every square metre of 100 potato seeds, then, covering in potato seed with the sand after boiled water sterilization cooling, sandy soil to exceed 3 centimetres of potato seed top, agricultural film in upper cover, by tight for agricultural film four limit pressure, heat and moisture preserving. Heat and heat to fiery pit on time, make under film temperature in seedbed be maintained at 18-25 DEG C. Water after emerging the dry and wet degree according to sandy soil, want to sprinkle water to bed surface in time, ensureing that soil has enough humidity, be beneficial to emerge and growth of seedling, temperature in the shed not can exceed that 25 DEG C all the time, never burn seedlings, prevent excessive growth, nurturing staff, during to field planting leaf age be SANYE wholeheartedly, height of seedling 15 centimetres is advisable, and the seedling brought out can pluck 2-3 stubble.

3, the preparation before field planting. Soil pesticide, preventing and treating subterranean pest-insect with phoxim 200 milliliters, mixes fine earth 15 kilograms and uniformly applies in field, mainly prevent and treat cutworm, wireworm, Holotrichia diomphalia Bates etc. for every mu before plowing. When whole ground basal dressing plows, diammonium 25 kilograms, potassium sulfate 10 kilograms are executed in every mu of field, if not having the field that the autumn applies fertilizer, the spring executes high-quality farm manure 4000 kilograms, plough under 20 centimetres, underground, and rake a kind of farm tools is smooth. Ridging row spacing 30 centimetres, ridge is high 30 centimetres, furrow width 20 centimetres, ridge face width degree, highly wants uniformity.

4, field planting. The field planting optimum time is on May-15 on the 5th. First pouring water before field planting method field planting, the depth of water does not get higher than top, ridge, when water oozes lower groove face 2/3, wears rain boots hyposulculus field planting, and method adopts interpolation. Namely after first manually being plucked by the seedling cultivated, left hand takes Radix Ipomoeae Seedling, and the right hand bends 90 degree in potato Seedling about 5 centimeters, deep from face, ridge top down pressing 3 centimetres, then finger cheats earthing pressure sternly, within 5-7 days, fills a water again. Plantation density spacing in the rows 25-30 centimetre, line-spacing 50 centimetres, every cave 1 Seedling, every ridge field planting a line, mu is kept a full stand of seedings 4500-5500 strain.

5, field management. Cultivation and banking before buddingging in time in weeding, ridging 2 times, and suitably increase and widen face, ridge. Topdressing pours water comes into bloom according to increment, and mu executes carbon ammonium 30-40 kilogram. Method is uniformly to spread manuer in holes from Seedling 5-7 centimeters scuppit in both sides, face, ridge, then pours water, and mid-term suitably pours water according to soil dry-wet situation, and the later stage is advisable not pour water. Foliage dressing Ruo Yese has yellowing phenomenon, should spray potassium dihydrogen phosphate in time, each 100 grams every mu. Pinching draws rattan for preventing rattan from taking root, and should draw rattan in time, and growing way wants pinching when crossing prosperous, to promote that tuber expands. The prevention and control of plant diseases, pest control, it has been found that when epidemic disease, brown spot, every mu of timely thiophanate methyl 100 grams or Mancozeb 100 grams are to the spraying of 40 kilograms of water.

Technique effect

The solution have the advantages that, adopt technique scheme, it is possible to achieve the achievement of Radix Ipomoeae high yield, this mode is not only convenient for operation, and can reach highly efficient and productive, be conducive to quickly breeding to go out high yield Radix Ipomoeae, have very good effect for Radix Ipomoeae diseases prevention, insect protected, high yield.

Detailed description of the invention

2, nursery. Seedbed area is generally with 6 square metres conveniently, north orientation south is sat in seedbed, seed selection potato selects " 868 " Radix Ipomoeae of strange land high yield and high quality to make mother's kind, and every mu of land for growing field crops needs 2 square metres of seedbeds to carry out nursery, sowing before and after April 5, the potato seed chosen is erected on bed surface sandy soil, covering in potato seed with the sand after boiled water sterilization cooling, sandy soil to exceed 3 centimetres of potato seed top, agricultural film in upper cover, by tight for agricultural film four limit pressure, heat and moisture preserving. Heat and heat to fiery pit on time, make under film temperature in seedbed be maintained at 18-25 DEG C. Want to sprinkle water to bed surface in time, nurturing staff, during to field planting leaf age be SANYE wholeheartedly, height of seedling 15 centimetres is advisable, and the seedling brought out can pluck 2-3 stubble.

3, the preparation before field planting. With phoxim 200 milliliters, mix fine earth 15 kilograms and uniformly apply in field, mainly prevent and treat cutworm, wireworm, Holotrichia diomphalia Bates etc. for every mu. When whole ground basal dressing plows, diammonium 25 kilograms, potassium sulfate 10 kilograms are executed in every mu of field.

4, field planting. Carried out field planting-15 days on the 5th May, first pour water, when water oozes lower groove face 2/3, after manually being plucked by the seedling cultivated, left hand takes Radix Ipomoeae Seedling, and the right hand bends 90 degree in potato Seedling about 5 centimeters, deep from face, ridge top down pressing 3 centimetres, then finger is cheated earthing pressure sternly, within 5-7 days, fill a water again.

5, field management. Cultivation and banking before buddingging in time in weeding, ridging 2 times, and suitably increase and widen face, ridge. Uniformly spreading manuer in holes from Seedling 5-7 centimeters scuppit in both sides, face, ridge, then pours water, and mid-term suitably pours water according to soil dry-wet situation, and the later stage is advisable not pour water. Foliage dressing Ruo Yese has yellowing phenomenon, should spraying potassium dihydrogen phosphate in time, pinching draws rattan for preventing rattan from taking root, and should draw rattan in time, when the prevention and control of plant diseases, pest control finds epidemic disease, brown spot, every mu of timely thiophanate methyl 100 grams or Mancozeb 100 grams are to the spraying of 40 kilograms of water.
