Abstract

The invention relates to a vegetable-purpose peanut producing method in a steel tube greenhouse. The vegetable-purpose peanut producing method in the steel tube greenhouse comprises the steps that 1 a standard steel tube greenhouse is constructed; 2 base fertilizer is fertilized firstly when a greenhouse film is covered, and four bed flatting is done; 3 geothermy warming lines are paved on each bed;4 sowing is conducted in early January; 5 ditching and soil covering are conducted through a small-sized ditcher when the sowing is finished; 6 straws and maize straws are covered on a 20 cm area vacating form the greenhouse border, white mulching films are covered on the bed surfaces and furrows, the white mulching films are pressed tightly, and the greenhouse is sealed to keep warm after the mulching films are covered well; 7 when the greenhouse is sealed, the geothermy warming lines are started for heating and urging seedlings to emerge; 8 when all the seedlings emerge, urea fertilizer for seed bed with the mass percentage concentration to be 0.2% is fertilized additionally at morning in a sunny day; 9 tender peanuts can be pulled up and picked to appear in the market continuously in the middle of April. According to the vegetable-purpose peanut producing method in the steel tube greenhouse, the peanuts can be pulled up and picked to appear in the market continuously in the middle of April, and the normal cultivating and picking period are advanced by more than 1 month compared with that of the open-field mulching film peanuts.

Description

The method of dish peanut is produced in a kind of steel tube greenhouse

Technical field

The present invention relates to a kind of method of producing dish peanut.

Background technology

In the prior art, dish peanut in spring general dish open country film-mulching cultivation method, its picking time, picking time was more late generally after mid-May, and late spring damage by disease and insect generation is more, needs to use relatively large agricultural chemicals.

Summary of the invention

In order to overcome the above-mentioned deficiency of the method for existing production dish peanut, the invention provides a kind of method of producing dish peanut in steel tube greenhouse, its picking time does not need to use agricultural chemicals early, substantially.

The technical scheme that the present invention solves its technical problem is: a kind of method of producing dish peanut in steel tube greenhouse, comprises the following steps:

1.. build wide 8m, the transmeridional standard steel tube greenhouse of long 44 ~ 75m, do the front upper horticultural covering film of furrow in mid or late December, airtight intensification after upper horticultural covering film;

2.. first basal dressing after upper horticultural covering film, institute's basal dressing is: apply organic commercial fertilizer 200kg/ mu, compound potassium sulfate fertilizer 30kg/ mu; Turn over after having executed base manure and smooth, do furrow afterwards, 20cm is respectively stayed in the canopy limit of width wholely, and remaining 7.6m on average divides work four furrow, and four furrow are flat furrow;

3.. every furrow lay 6 road underground heat heating wires, and the distance between adjacent heating wire is 20cm, and the depth of burying of heating wire is 2 ~ 3cm;

4.. in early January sowing, adopt early-maturing and large scarlet kind, every drill seeding kind 7 row, adjacent plantation row by geothermal-warming line interval, the peanut seed that program request has been sprouted, spacing in the rows 10 ~ 15cm on same plantation row, sow on rear furrow face and spread fertilizer over the fields phoxim granule, control soil insect;

5.. after having sowed, to ditch earthing with Mini-type ditching machine, ditch depth 30 ~ 40cm, four furrow in step 2 are separated by ditch, and the thickness of earthing is to lose seed and heating wire is as the criterion, furrow face of raking after earthing;

6.. the 20cm mulching straw that canopy limit is vacated or maize straw, furrow face connects ditch and covers white mulch film, and presses tight, builds rear airtight booth thermal insulation;

7.. after airtight booth, start to enable geothermal-warming line to heat and urge seedling, soil temperature controls at 15 ~ 20 DEG C, after seed major part is emerged, concentrated rupture of membranes chooses seedling, with hack compacting cut, and starts stopping and heating, opening to the weather forecast minimum air temperature lower than 1 DEG C or when having frost heats to soil temperature 15 ~ 20 DEG C again, stops heating when the weather forecast minimum air temperature is removed higher than 1 DEG C or frost again;

8.. after all emerging, to chase after the morning water the urea seed manure that mass percentage concentration is 0.2% at fine day, water one time again after existing bud, full-bloom stage waters one time again, waters sufficient water while watering fertilizer; Fine ventilation is robbed in employing of ventilating seedling stage, and southern side leads to the ventilation of little wind;

9.. start tender peanut to mid-April and can pull up harvesting listing successively.

Beneficial effect of the present invention is: can start to pluck listing to mid-April, do sth. in advance more than 1 month than the open country mulch film Spring Peanut conventional cultivation picking period, and now market still belongs to blank; And can about 400kg be reached according to method per mu yield dish peanut of the present invention, per mu yield value reaches more than 20,000 yuan, and economic benefit is fairly obvious; And early spring, damage by disease and insect occurred few, did not need to use other agricultural chemicals, more can the product of production safety high-quality.

Embodiment

Below in conjunction with embodiment, the present invention is described in further detail.

Produce a method for dish peanut in steel tube greenhouse, comprise the following steps:

1.. build wide 8m, the transmeridional standard steel tube greenhouse of long 44 ~ 75m, do the front upper horticultural covering film of furrow in mid or late December, airtight intensification after upper horticultural covering film;

2.. first basal dressing after upper horticultural covering film, institute's basal dressing is: apply organic commercial fertilizer 200kg/ mu, compound potassium sulfate fertilizer 30kg/ mu; Turn over after having executed base manure and smooth, do furrow afterwards, 20cm is respectively stayed in the canopy limit of width wholely, and remaining 7.6m on average divides work four furrow, and four furrow are flat furrow;

3.. every furrow lay 6 road underground heat heating wires, and the distance between adjacent heating wire is 20cm, and the depth of burying of heating wire is 2 ~ 3cm;
