When will Snow Red be broadcast? How to plant it?

Winter and spring sherry red is usually planted in late September, and autumn sherry red is planted in late July. It depends on the variety characteristics, edible requirements and stubble arrangement.

Second, the planting method

1. Seedling raising: Seedling raising is an important step in the cultivation of xuelihong. The soil for raising seedlings should be very fertile, and it is best to use farmyard manure compost to raise seedlings one month before raising seedlings. Tillage well before seedling raising, and use sunlight to achieve certain disinfection effect. The soil should be selected in a fine place, and the seeds don't need to be buried very deep, just 2-3 cm, so that the seeds can absorb soil nutrients well and breathe the air, which is helpful to grow seedlings faster.

2. Soil preparation: the requirements for the transplanted soil are not high, as long as it is fertile, the land should be composted and the base amount should be larger. Secondly, the land should be leveled and drained well. Each bar is controlled to be 1.5 meters wide, and the middle drainage ditch is controlled to be much wider than its own feet, so as to ensure convenient walking in daily management. Weeds and the like that have been cleaned should be taken away, and composting is not allowed, otherwise it is easy to produce germs.

3. Planting: Planting time should be earlier. At this time, Xuelihong has the best vitality and high survival rate, and the time should be controlled at about 8- 10. It is better to have some soil on the fixed seedlings, which can effectively protect the seedlings. It is suggested to transplant at the height of 12- 15 cm. At this time, the seedlings have just entered the growth period, and too dense is not conducive to growth. The spacing between transplanted seedlings should be controlled at 20-30 cm, and a certain amount of water must be poured after transplanting.

4. Fat water: Fat water is the decisive factor for the later growth of Xuelihong, and it must be sufficient. Fertilization is generally applied with nitrogen fertilizer mixed with phosphorus and potassium fertilizer, mostly for nitrogen fertilizer stations. In order to ensure the early growth of seedlings, a certain amount of urea can be applied, and a small amount of fertilizer should be applied in time after planting for one week. The middle stage is the most diligent time for fertilization, and it usually needs to be applied 2-3 times. Fertilization is not required for half a month before picking. After each fertilization, spray an appropriate amount of water according to the dry humidity of the soil.

5. Insect prevention: This is the place where Xuelihong needs attention, which is easy to reduce production. The main harm of snow red is mainly concentrated on pests, such as aphids, which are particularly frequent and difficult to find. It is generally found that the leaves of Xuelihong are easy to change color, so everyone should check the plants in time. Pesticides should be used to kill pests in time after they are found, because it is difficult to find them manually. Other diseases occur less, as long as the humidity and moisture are not too high.

Extended data:

Control measures of diseases and insect pests of xuelihong

The main pests and diseases are virus diseases and aphids.

1, Prevention and Control Principle Implement the plant protection policy of "prevention first, comprehensive prevention" and implement the pollution-free management principle of "agricultural prevention and biological prevention first, reducing chemical prevention and advocating physical and biological prevention". Focus on the prevention and control of aphids and viral diseases.

2. Pesticide control of viral diseases In the early stage of the disease, virus inhibitors such as 20% virus A wettable powder 500 times solution or 2% mycodox water solution 250 times solution were used together with growth promoters. Use 10% primary net wettable powder 1500 times solution or 0.36% matrine aqueous solution 1000 times solution to control aphids. Use drugs alternately, and prohibit the use of highly toxic and residual pesticides.
