Abstract

The invention relates to a growing method for yellow-skin onions. Seeds are sowed at September 10 to 15, and seedbeds are chosen to be constructed in greenhouses at a high elevation; before seeding, about 2000kg of decomposed manure, 30kg to 40kg of phosphorus-potassium compound fertilizer and 7kg to 10kg of phoxim granules are applied per Mu, and after uniform tillage and raking, high plots which are 1m to 1.5m wide are formed; before seeding, bottom water is sufficiently poured in the seedbeds; during seeding, seeds are scattered evenly; after seeding, mulching films are spread, a root trickle irrigation system is opened for watering for 30 minutes each day, and the mulching films are opened for appropriate ventilation after evening each day. The growing method for yellow-skin onions adopts the ecological greenhouses for growing, which is favorable for management, so that the affection of environmental factors on yellow-skin onions in the process of growing is little, and scientific management ensures that yield is better ensured, and when the growing method for yellow-skin onions is utilized to grow yellow-skin onions, yield can be increased by 10 to 20 percent.

Description

A kind of implantation methods of yellow onion

Technical field

The present invention relates to proportion of crop planting field, particularly relate to a kind of implantation methods of yellow onion.

Background technology

The micro-Huang of yellow onion scale meat and soft, organize fine and closely woven, pungent is denseer, oblate, diameter 6 ~ 8cm, comparatively shelf-stable, transport, precocious in ripe, output is lower than red skin kind, but quality is better, can do dehydration processing; At present adopt outdoor field planting, comparatively large by such environmental effects, there is growth cycle long, the problem such as yield poorly more.

Summary of the invention

The object of the invention is to be for the deficiencies in the prior art, provide a kind of and reduce yellow onion growth cycle, improve the cultivation method of output.

In order to solve the problem, the technical scheme that the present invention takes is: a kind of implantation methods of yellow onion, comprises the following steps:

(1) build Ecological Greenhouse, be provided with root and drip irrigation system, whole day lighting apparatus, thermometer;

(2) sow in 10-15 day in September, seedbed is selected to carry out in the higher booth of physical features, before sowing, execute decomposed manure about 2000kg for every mu, phosphorus potassium complex fertilizer 30-40kg, phoxim granule 7 ~ 10kg, plough even rake thin, make the high furrow that 1 ~ 1.5m is wide, before sowing, vola water is watered to seedbed, during sowing, seed is sprinkled evenly, after planting cover mulch film, open the root system of dripping every day and water 30 minutes, open mulch film at dusk every day suitably to ventilate, within 5 ~ 7 days after neat seedling, spray with 70% thiophanate methyl, 800 times of liquid or 50% carbendazim, 500 times of liquid, continuous control 2 ~ 3 times, about 7 days, interval.Treat that rice shoot has 3 leaf 1 hearts, when plant height 20 ~ 25cm, the thick 0.6cm of false stem, seedling age 50 ~ 55 days, get final product field planting;

(3) field planting first half of the month is to planting greenhouse basal dressing, execute well-rotted farmyard manure 1330 ~ 3340kg for every mu, then be mixed into superphosphate 16-20kg and 5-10kg potash fertilizer, when field planting, seeding row spacing is 15x20cm, water immediately after field planting, rear spray herbicide, ensures that the temperature of booth is at 12-20 DEG C, the daily 2-3 of not having days opens root and drips system, each half an hour, night and cloudy day open lighting apparatus, ensure the light application time of more than 14h every day;

(4) squama footpath is expanded and is imposed disposable fertilizer in first 15 days, executes urea 20-30kg for every mu, and potassium sulfate 10-20kg bis-ammonium 10-15kg, has executed fertilizer and fully watered afterwards, within 5-7 days, afterwards with 10% Imidacloprid, 1000 times of liquid or dimethoate emulsifiable concentrate 800 times of liquid spraying control thrips, prevents and treats 2 ~ 3 times; Downy mildew and purple spot is prevented and treated 2 ~ 3 times with 70% thiophanate methyl wetting powder, 800 times of liquid or the alternating spray such as 75% tpn, 600 times of liquid or 65% mancozeb, 600 times of liquid.Weeding in vegetative period 2 ~ 3 times after spring;

(5) pluck and take 24h illumination in first 15 days, reduce irrigation times, do not have 6-7 days and open once root and drip system, each 10 minutes.

Based on the implantation methods of above-mentioned a kind of yellow onion, it is characterized in that: said 10% Imidacloprid 1000 times of liquid can replace with dimethoate emulsifiable concentrate 800 times of liquid sprayings, and described 70% thiophanate methyl wetting powder, 800 times of liquid can replace with 75% tpn, 600 times of liquid or 65% mancozeb, 600 times of liquid.

Beneficial effect of the present invention: the present invention adopts Ecological Greenhouse to plant, not only be beneficial to management, make yellow onion less by such environmental effects in the process of growth, scientific management makes output more secure, utilize the present invention to plant yellow onion, output can improve 10%-20%.

Embodiment

An implantation methods for yellow onion, comprises the following steps:
