Next, let's have a look with the editor.

First, how to select red seeds in snow?

The storage period of snow red seeds is 5 years. The seeds harvested in that year could not be planted in that year, and even if they were planted, the emergence rate was very low, or even did not emerge at all. Therefore, it is better to choose seeds that have been stored for more than one year to grow cabbage.

There are many varieties of Xuelihong, which can be selected according to the actual local conditions. For example, some varieties are heat-resistant and some are cold-resistant. In addition, we should also pay attention to the selection of varieties with better resistance and faster growth.

Second, what are the seedling raising methods of Xuelihong?

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. Diseases and insect pests

The prevention and control of red diseases and insect pests in snow must be done well, otherwise it is easy to reduce production. The harm of snow red is mainly insect pests, especially aphids. If you find that the red leaves in the snow are not the right color, remember to check the plants in time.

The above is the introduction of Xuelihong, the planting of Xuelihong is determined according to the varieties and food requirements, the winter and spring varieties are generally planted in September, the autumn varieties are generally planted in July, and the spring varieties are generally planted in February-April. When planting snow red, farmers must choose a good seed and raise a good seedling.
