How to grow rapeseed well

1. Maintenance methods

1. Temperature: It can be seen from its main distribution areas that it likes higher temperatures, and twenty to thirty degrees is more suitable. It is not very cold-resistant, so it is not widely grown in the north. If you want to grow it as an ornamental plant, you need to pay attention to cold protection.

2. Light: It likes light very much. If it is kept in a dark environment for a long time, its growth will be very slow and it will be prone to some diseases. Therefore, whether it is during the growth period or during the winter, we must try our best to provide sufficient light.

3. Watering: It is a moisture-loving variety. Especially when it’s flowering time. Its flowering period is generally about thirty days. During this stage, watering must be timely. During the pod stage, watering is required one or two times.

4. Fertilization: The main method used is foliar fertilization. First, during the flowering period. At regular intervals, you need to spray some fertilizer water containing trace elements. In addition, superphosphate is also needed for foliar application.

2. Breeding techniques

1. Reproduction: The most commonly used method is sowing. Because its seeds are relatively small and not easy to germinate, it is necessary to select a good quality substrate and pay special attention to the adjustment of the surrounding environment after sowing so that they can germinate more easily. The row spacing can be controlled at twenty centimeters. After sowing, the soil covering thickness can be about one centimeter. Then, it is better to control the temperature between eighteen and twenty degrees.

2. Repotting: Rapeseed flowers can also be placed at home as potted plants, so you need to pay attention to regular repotting. When choosing soil, there are two factors that need special attention. One is the degree of fertility, that is, how much nutrition it contains, and the other is whether it is loose.

3. Problem diagnosis and treatment

1. Disease: There may be "sclerotinia disease", which often appears during the flowering and fruiting periods and can be controlled by carbendazim. There may also be "viral diseases", which can be prevented and treated with dimethoate emulsion.

2. Pests: One of the main types of pests is "aphids", which not only cause harm themselves but also spread diseases. They can be dealt with by using omethoate and other drugs.
