The latest course of field management techniques and methods of rape

Oilwheat is a variety of lettuce, a vegetable variety cultivated in recent years, planted with different management from lettuce. Oil-wheat vegetables mainly feed on leaves, so the characteristics of fertilizer and water requirements are different. Then, the growth characteristics of wheat and oil vegetables determine the management content. Weather and environment determine the focus of pest control. The specific management work content is as follows, please pay attention.

1. Transplanting

Long leaves 5 to 6 start transplanting, before transplanting to flood irrigation infiltration, soil moist fluffy seedlings. Don't water it into mud soup, you can't transplant it with soil. As little damage as possible. Nursery seedlings, take seedlings can be easier not to water, lest the nutrient soil loose. Transplanting should be loose, not dense. About 20 cm row spacing, 10 cm plant spacing. It can be used flexibly. After transplanting, the seedlings were slowly planted for about 10 days. Unfertilized water.

2. Fertilization

Field base fertilizer should be applied about 1200 jin of circle fertilizer. Can add some plant ash about 200 jin, furrow application in the row absorption and utilization rate is higher, the whole field is scattered, fertilization is not too concentrated, but improve the soil is very good. Topdressing is mainly nitrogen fertilizer, when the plant grows to 15 cm high, it can be sprayed with 1:300 potassium dihydrogen phosphate solution to supplement fertilizer. 10-15 kg of urea can also be dissolved in water for irrigation.

3. Drainage and irrigation

After 10 days of transplanting, the seedling can be watered once after the root system grows normally. If the soil moisture is good, you can delay watering. Youmai needs enough water to keep its leaves growing, but it is necessary to prevent excessive humidity from causing downy mildew, or water damage to the base leaves. About 60% soil moisture is enough.

4. Diseases and pests

Downy mildew often occurs, mainly affecting stems and leaves, or near the base of leaves, mainly producing water-soaked spots, extending large areas of rot, white mold appears. Spray 200 times of high lipid film (emulsion) before onset of disease, once every 10 days. At the early stage of the disease, 75% chlorothalonil wettable powder was sprayed with 500 times solution. Severe use of 58% nail cream·manganese zinc wettable powder 500 times solution spray. Aphids are the main pests, sucking leaves, a large number of occurrence of the use of 50% anti-aphid WP or 50% fenitrothion emulsion 1000 times solution control.

5. Intertillage and weeding

Weeds should be used immediately after planting, but it is best to use botanical herbicides. Weeds can be manually removed when there are few weeds, and herbicides should be used as little as possible. Leafy vegetables are prone to phytotoxicity. Intertillage can be done after rain to avoid hardening.

These are the specific management contents. If you have management experience, you can refer to them for implementation. Hope to help everyone, thank you for your support.
