Matters needing attention in the latest rape planting

Rapeseed is a vegetable of Brassica genus, belonging to Cruciferae. Rapeseed is very common in our life. You may not know that rape flower is rape flower. Rape flower stem seeds have a very large role, flower stem can be eaten, seeds can be pressed into rapeseed oil after drying, rape contains rich plant cellulose, can promote digestion. So what should we pay attention to when planting rape? Let's take a look at it together with Xiaobian.

1. Light

Light duration and light intensity will have certain effects on the growth of each part of rape. If there is not enough light during the growth process, the root elongation and expansion speed of rape will slow down. Affect root nutrient absorption and transportation, late growth is hindered, reduce yield. Sufficient light played a greater role in promoting the growth of rape, enhancing photosynthesis of leaves and improving nutrient accumulation.

2. Water

Under the condition of good growth of rape, the plant is larger and the leaves are more fertile, so the water required for growth will also be larger. However, the water requirement varies at each stage of growth, for example, when the seedling stage requires little water, as long as the soil is wetted when the temperature is high and the soil is dry. The flowering stage is the stage where water demand is the largest. At this stage, we should ensure that the water content in the field is not less than 75%.

3. Soil

Rape can be eaten except for its roots. It belongs to crops with straight roots. The roots of rape are very strong and branched. The taproot can enter deep soil. Therefore, rape planting must be in fertile, deep soil litigation, rich in organic matter, water and fertilizer strong soil. Soil PH partial acid more suitable for rape growth, can improve the oil content of rapeseed.

4. Temperature

Rapeseed likes cool but does not tolerate high temperature. It is a very cold-resistant vegetable. According to experiments, rape seeds can germinate normally in 4 degrees environment. However, the most suitable temperature for rape growth is about 22 degrees Celsius, and each growth stage has different temperature requirements. The suitable temperature for flowering is about 17 degrees Celsius, and the development period 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 nutrients in the plant and improve the quality.

5. Boron fertilizer

Rape has a high demand for boron fertilizer, but no matter where it is, boron in the soil is almost negligible. And boron deficiency in rape growth will lead to flowering but not fruit, so we should pay attention to the application of boron fertilizer in management. If boron fertilizer is lacking in base fertilizer, foliar fertilizer should be sprayed at flowering stage.

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. Perhaps other crops do not need boron fertilizer, but rape is essential, so we must pay attention to the application of boron fertilizer. In order to make rape more good growth and development, improve yield. This article is for reference only. If you want to know more relevant information, please continue to pay attention to it!
