Points for attention in planting Fangfeng

Windproof is mainly used for the treatment of cold, cold and skin diseases, in our lives are often used, but we are not very familiar with it, perhaps limited to hearing the term windproof vaguely as if they have seen it, but where do you come windproof efficacy and use range has been developed, so many people are invested in the windproof planting industry, appreciation Some people in their own balcony will also be in the upper two. Today, pro-agricultural network to teach you about windbreak in the process of planting a few things that need special attention, I hope can help you.

1. Methods of seed treatment

If it is to use seeds for sowing, then we first need to find some river sand, then wet the river sand, stir the seeds in the river sand, so that each seed is evenly coated with a layer of sand, and then place the treated seeds in an environment with a suitable temperature ratio for fifteen to twenty days, and wait until the seeds sprout.

2. The way of sowing seedlings

There are two ways to sow windbreaks, one is to sow with seeds, and the other is to sow with tubers. Let's start with seed sowing. Furrow the land at intervals of 20 to 25 centimeters. Then sprinkle the seeds evenly in the furrows. The depth of the furrows should not be higher than four centimeters. It is best to cover the seeds with a thin layer of soil. Tuber planting first requires cutting the dug tubers into small sections, each section is about 10 cm, then the land is furrowed at a distance of 25 cm, arranged according to the spacing of each plant 10 cm, and finally covered with a layer of soil to cover the seeds.

3. Scientific fertilization methods

In planting honey, nitrogen fertilizer needs to be applied well. Generally, the amount of farm manure needs to be about 2,500 kilograms. Secondly, it needs to be sprinkled with 20 to 30 kilograms of phosphorus fertilizer to supplement fertility. When the windbreak seedlings grow to three or four centimeters in the field, we must first remove the weeds in the field, and then apply about 60 kilograms of phosphorus and potassium fertilizer, or water for irrigation. The second topdressing is to wait until the seedlings develop to about 15 cm, when it is mainly to raise seedlings, so it is mainly urea and potassium fertilizer. The last topdressing is when the tubers of windbreak swell. At this time, we mainly spray the medicinal herb Gendaling, and apply an average of 20 kg of boron fertilizer per mu.

4. Effective pest control

Common diseases and insect pests of windbreak include powdery mildew, root rot, spot blight, yellow wind butterfly, yellow wing fennel moth and carrot aphid. Powdery mildew mainly occurs in summer and autumn, which is very harmful to the leaves of windbreak. The control methods we adopt are to increase phosphorus and potassium fertilizer, strengthen light and permeability. 50% thiophanate-methyl 800-1000 times liquid spray is used for prevention and control when the disease occurs. Root rot is mainly harmful to the root is to do a good job in advance drainage measures, timely discharge of water in the field. Yellow butterfly, yellow wing fennel moth, carrot microtube aphid are several of the most serious pests, we generally use trichlorfon solution or dichlorvos solution for spraying, every seven or eight days spray once, continuous spray about three times can be.

5, the correct way to harvest

Windbreak can be harvested in November of the second year of planting this year. Generally, the branches and leaves of windbreak grow to 300 cm high, so they can be harvested when the branches and leaves slowly turn yellow-green. If you are worried about not having an account number, I have already found a plant in the field to dig up the soil next to it to see if the tubers grow. If the tubers are 30 to 35 cm long, you can rest assured to harvest them.
