Mustard egg is an indispensable material on our daily dining table, and it is also a famous special vegetable in China. Mustard is rich in nutrition, and eating more is good for your health. Our method of making mustard here is mixing or frying. It tastes crisp, soft and delicious. Personally, I think cold salad is very good. The hometown of mustard can be said to be Guangdong. Because Guangzhou was the first place to grow kale. Since then, the demand of the mayor/market has continued to increase, and the northern region has also begun to introduce planting. Kale is grown in Guangdong, which used to be only for the domestic market, but now it is mainly exported.

Mustard likes heat but is not cold-tolerant, and plants with temperature below 19 will be stunted. The most suitable temperature for sowing is about 27℃, and the temperature in the middle stage of stem and leaf growth is best controlled at about 26℃. At this time, the temperature exceeds 29, and the temperature at night cannot be lower than 16. Otherwise it will affect the normal development of mustard moss. Mustard seed means that the suitable temperature for the whole growth period is 16~ 27. According to different varieties, the suitable temperature is also different. Please choose a variety suitable for local temperature planting.

The longer the illumination time, the more suitable for the growth and development of Chinese kale. Chinese kale can't be planted in the shade, and insufficient light will lead to the slow development of mustard seed buds and affect the yield. Mustard coating device relies on leaves to make organic matter for photosynthesis and self-supplement nutrition. Therefore, if the yield is high, mustard eggs should be completely photosynthetic, and it is best to irradiate them for about 12 hours all day.

Mustard likes warm and humid soil environment and is drought-tolerant. The water requirement at seedling stage is relatively high, and the suitable soil water content is about 80%. Chinese kale is not afraid of high soil moisture, but it is best not to let the soil moisture exceed 89% in order to completely absorb plant roots and achieve high yield. 78% of soil water content is appropriate in twilight. During the whole growth period of mustard, the soil moisture regulation is 70% ~ 90%.

Chinese kale requires more soil than other plants. Generally speaking, thick soil layer, loose soil and fertile soil are the best. Soil with high sand content is more suitable for the growth of Chinese kale, while loess sandy land is not suitable for the growth of Chinese kale. This kind of soil has poor repair ability, and the water evaporates quickly in summer, so it can't reach the soil moisture suitable for mustard growth, and drought is easy to affect the yield. Therefore, it is best to choose soil that keeps fertilizer and water.

If you choose land, first spread the base fertilizer on the ground. The base fertilizer is mainly farmyard manure, and 3500 kg and 30 kg of calcium phosphate are evenly spread on each acre. Just turn the ground when you turn it over. Turn over 25 cm, turn over the ground and dry for about a week. Drying can play a role in sterilization and disease prevention. Level the land with a rake in the sun, break up the big clods to make the soil thinner, then level the land with a lease, and don't press the land too tightly when you take it back with the lease. Will affect seed germination. Chinese kale varieties are divided into early maturity, middle maturity and late maturity. Generally speaking, early-maturing and medium-maturing varieties are more popular. Green mustard, Baihua mustard, mustard and other early-maturing varieties. Moderately mature varieties, such as mustard and mushroom mustard. These varieties are excellent varieties with strong disease resistance and easy planting. The growth period of early-maturing varieties is about 55 days, and that of middle-maturing varieties is about 70 days. It is necessary to choose suitable varieties according to the planting environment.
