Planting technique of Citrus chinensis

Xuelihong is a common vegetable in the north, and it is generally a seasonal vegetable in the south, but at present, with the acceleration of the integration of the north and the south, it also appears slowly and frequently on the table in the south. So how on earth should this vegetable be grown? Next, let's learn about it together with the pro-agriculture network.

1. Raising seedlings

Raising seedlings is an important step in planting Xuelihong. The soil for raising seedlings should be very fertile, and it is best to use farm compost to raise seedlings one month before raising seedlings. Ploughing well before raising seedlings, the use of sunlight to achieve a certain disinfection effect. Select the soil to choose a relatively fine place, the seeds do not need to be buried very deep, 2-3 cm is good, so that the seeds can well absorb soil nutrients and breathe air, which is conducive to faster seedling success.

2. Land preparation

After transplanting, the requirement of the soil is not high, as long as it is a little more fertile, the land should still be compost, and the base quantity should be a little larger. Secondly, the land will be leveled into strips, drainage should be done well, each one is controlled at 1.5 meters wide, and the middle drainage ditch is more than one foot wide, so as to ensure that it is convenient to move around during daily management. The weeds cleaned up should be taken away and should not be composted, otherwise it is easy to produce pathogens.

3. Colonization

The time of setting is a little earlier, when the vitality of Xuelihong is the best, the survival rate is high, and the time is controlled at about 8-10:00. The fixed value of the seedlings had better have a certain amount of soil, so as to form effective protection for the seedlings. It is recommended to transplant at about 12-15 cm, when the seedlings are about to enter the growth stage, and it is not conducive to growth if they are too dense. The transplanted seedlings should be controlled at a distance of 20-30 cm, and a certain amount of water must be irrigated after transplanting.

4. Fertilizer and water

Fertilizer and water is the decisive factor in the later growth of Xuelihong, so there must be plenty of fertilizer and water. Fertilization is generally applied with nitrogen fertilizer mixed with phosphorus and potassium fertilizer, and most of them are nitrogen fertilizer stations. In order to ensure the growth of seedlings, a certain amount of urea can be applied in the early stage, and a small amount of urea should be applied in time one week after planting. The middle stage is the most diligent time for fertilization, which usually needs to be applied 2-3 times. There is no need to apply fertilizer half a month before picking. After each fertilization, spray an appropriate amount of water according to the soil dry and humidity.

5. Pest prevention

This is what Xuelihong needs to pay attention to, and it is easy to reduce production. The main harm of snow red is mainly concentrated in insect pests, such as aphids occur more frequently, and it is not easy to find. Generally found that the snow red vegetable leaves have a tendency to change color, we should go in time to check the plant. After finding the species of pests, it is necessary to remove them with chemicals in time, because manual work is very difficult to find. Other diseases occur less, as long as the humidity and moisture are not too high.

At present, the market of snow red is slowly opening up like the south, and the taste is also more suitable for the taste of southerners. When it becomes popular, there must be a good market, so we must pay attention to planting this so that we can have a good harvest.
