Americium is one of the high-efficiency cash crops with low planting costs, simple methods of planting, acre production of more than 10 years' worth, tens of thousands of dollars, and good prospects for cultivation. The following is a detailed field management technique for high-yielding beryllium cultivation, to which you can refer。
1. Cultivation of seedlings
In addition to the choice of good varieties, a nursery should be set up to provide seedlings, the most suitable of which would be in june and the birth of a child for about three months. Start-up on site, with a range of 16. 5 cm x 16. 5 cm。
2. Portability
The acreage is grown on the high tide of sandy soil, which is preceded by several ploughs of pine soil and the removal of impurities from the soil, full tan (one to two months) and application of manure or calcium phosphate to mature farmers and 30 kg of potassium chloride. The manure is spread and then the plough is turned over, while the pie fat is fed with water from 8 to 10 days to mix calcium phosphate with potassium chloride and seedlings in the gutter (30-40 cm deep)。
3. Reasonable secrets
The planting period is most suitable for autumn planting, with short harvest times and high survival rates. The range of the plant is 25 cm x 160 cm. Cultivation takes place in two-and-a-half roots, which are fixed in a puddle, sprouts towards the mid-line, then the soil is 5-6 centimetres, and the root water is pressed down。
4. Fertilizer water
When seedlings are planted, water is pumped using ditch irrigation. The first fertilisation in 20 days. After planting for 40-60 days, fertilization is applied every 25-30 days, with 25-50 kg of compound fertilizer or 10-20 kg of urea plus 6-12. 5 kg of potassium chloride. Fertilization is performed every 25 days from the time of planting to the time of extraction。
5. Fertilizer during harvest
Fertilizers are applied every 15-20 days, 20 kg urea per acre and 12. 5 kg potassium chloride per acre. At the same time, care must be taken to open four-side ditches and fields, dry water in the rain and water in the clear。
6. Deciding mother
After planting for about five to six months, the seedlings smoke the last batch of tubers, which are up to 0. 8-l cm in length, with the selection of the mother, usually two to three strong, old and infested ones, and the rest of them removed。
7. Combating pests and diseases
Among the most common diseases in the country are stasis and anthrax. The prevention of stasis can be carried out using 70 per cent of the 600 times of methyl tobuzin or 40 per cent of the more than 500 times the aerosol spray, every 10 to 15 days for seedlings, and every 5 to 7 days for saplings; the prevention of anthrax can be carried out by 70 per cent of the 500 times the liquid dyson manganese zinc, or 75 per cent of the bacteria can clear 600 times the fluid of humid powder or 80 per cent of the 80 per cent of the oxenthrax fumes of humid powder。
Viii. Employment
After three to four months of harvest, the seedlings begin to age, at which point they should all be removed, with only one potato left and then fertilized, usually twice a year。
The platinum is rich in nutrients and of good food value. The market demand has been very high in recent years, and many growers have grown it to become rich. These are techniques for the management of the platinum-rich fields, which the relatives who want to grow。
