Matters needing attention in rape planting

Rape is a vegetable of Brassica, belonging to Cruciferae. Rape is very common in our life. You may not know that rape is the flower of rape. Rape flower stem seeds play a very important role, the flower stem can be eaten, the seeds can be dried into rapeseed oil, rape is rich in plant cellulose, which can promote digestion. So what should we pay attention to when planting rape? Let's take a look at it with the editor.

1. Lighting

Light time and light intensity will have a certain impact on the growth of various parts of rape, if there is not enough light in the growth process, it will slow down the root elongation and expansion rate of rape. Affect the absorption and transport of nutrients in the root, hinder the growth in the later stage and reduce the yield. Sufficient light can greatly promote the growth of rape, enhance the photosynthesis of leaves and improve the accumulation of nutrients.

2. Moisture

When rape grows well, the plant is larger and the leaves are more fertile, so the water needed for growth will be larger. But the water requirement is different at each growth stage, for example, the water demand is small at the seedling stage, as long as the soil is wet when the temperature is high and the soil is dry. Flowering is the stage of maximum water demand, and at this stage we should ensure that the water content in the field is not less than 75%.

3. Soil

Rape is edible except for its roots and belongs to straight-root crops. The roots of rape are very strong and branched, and the main roots can enter deep soil. Therefore, rape must be planted on fertile, deep soil, rich in organic matter, and strong in water and fertilizer conservation. The pH value of soil is more suitable for the growth of rapeseed and can increase the oil content of rapeseed.

4. Temperature

Rapeseed likes cool and can not bear high temperature. it is a very cold-tolerant vegetable. According to experiments, rape seeds can germinate normally at 4 degrees. However, the most suitable temperature for rape growth is about 22 degrees, and each growth stage has different temperature requirements, the suitable temperature at flowering stage is about 17 degrees, and the development stage is slightly lower. It is also necessary to ensure that the temperature difference between day and night fluctuates greatly in order to make rape grow better, accumulate more nutrition in the plant and improve the quality.

5. Boron fertilizer

Rape has a great demand for boron fertilizer, but wherever it is, the boron in the soil is almost negligible. And boron deficiency in rape growth will lead to the phenomenon of flowering but not fruiting, so we should pay attention to the application of boron fertilizer in management. If there is a lack of boron fertilizer in the base fertilizer, foliar fertilizer should be sprayed during flowering.

The above five points are the precautions when planting rape. Planting is simple but management is not easy. In particular, the application of boron fertilizer is the most important, other crops may not have a high degree of need for boron fertilizer, but rape is essential, so we must pay attention to the application of boron fertilizer. In order to improve the growth and development of rape and increase the yield. This article is for reference only, if you want to know more related information, please continue to follow!
