Planting technology of oil, wheat and vegetable in greenhouse

Rape is similar to lettuce leaves, but it is a leafy vegetable while lettuce is a stem vegetable, and it tastes better than lettuce leaves. Let's follow the editor to learn the techniques of growing oil and wheat in the greenhouse.

First, sowing and raising seedlings

The soil in the greenhouse keeps a certain degree of wetness, sow the seeds of rape, then spread a layer of farm manure on the surface of the seeds, that is, the poop of livestock, and finally spread a layer of fine soil to cover the seeds, if the temperature is not particularly high, you can cover it with a layer of film for sprouting, and wait until 80% of the sprouts have already sprouted, otherwise the seedlings will be burnt out.

II. Colonization

Generally, five or six days after germination, colonization can begin. Generally, the distance between plants is about 20 centimeters, and the distance between rows is 15 centimeters. Planting at this interval will not only increase the yield of oil wheat, but also prevent some diseases caused by density. no, no, no.

III. Field management

The control of water and nutrients during the growth of rape. The growth process of rape needs a lot of nutrients, and the general way of fertilization is to spray potassium dihydrogen phosphate or other foliar fertilizer with water. Using greenhouse to grow, the most suitable growth temperature is 18 °to 25 °. The most common disease of rape is downy mildew, the most common pest and leaf worm. We usually use Purek or Metalaxyl manganese zinc wettable powder for prevention and treatment of downy mildew.

IV. Harvest

The time of harvest must be timely. If you eat it yourself, you can harvest ahead of time. At that time, the leaves are very fresh and tender, but if they are sold, they are usually harvested when rape grows 15 to 20 leaves. At this time, the leaves are the best.

In contrast, it is easier to grow rapeseed in the greenhouse than in the open air, and the temperature in the greenhouse can be artificially controlled. Farmers who want to plant can have a try.
