1. Preparation for broadcast
24 cm to 25 cm deep and flat. In the event of insufficient pre-broadcasting, 10 days of water should be provided。
2. Fertilizer formulation
The 25 kg ~ 50 kg of ammonium carbonate is equilibrated by 300 kg ~ 500 kg of chromosome weight per acre about 20 days in advance, sealed in the sun and modulated after full decomposition, and applied and rolled into the soil as the land was thrown。
3. Pre-scrotch processing
1 sterilized. 120 kg per acre and 400 times ~ 500 times wetting of the original species。
Two slices. Cut each potato into more than eight pieces. Due to their top advantage, multiple slices are made at the top, to the extent possible, with 10 mg/kg acceleroxin in a bag and 10 kg water impregnated for 5 minutes or 75 kg water sprayed。
Three tremors. The chips are placed flat on the scavenging soil, so that the potatoes are sprouts upwards, two centimetres above the soil and a layer of potatoes, three to four layers upwards and five centimetres thick, piled on the back of the sun, with a tight membrane cover, and seeding in 15 days。
The above-mentioned work should normally be done by mid-year, with a suitable 90-100-day life and delayed seeding due to the excessive expansion of potatoes at temperatures above 25°c and the cessation of the growth of tubers and the growth of chickens。
4. Seeding requirements
The earth is torn to one side by a ditch of 70 centimetres and 20 centimetres, deep at depths of 6 centimetres to 8 centimetres, and the potatoes are to be sprung up when they are planted, and the ground rises 10 centimetres to 15 centimetres. It covers the membrane, which after the budding membrane。
5. Field management
When they grow three to five leaves, care about aphids. In the early stages and during the flowering period, one fat was followed up, with 500 times more urea and 1 per cent magnesium added to phosphate. Special attention was paid to increasing field water in order to increase production during the period of poaching。
6. Timely harvests
The best potato quality in mid-june should be harvested in time。
7. Pest management
The disease of potatoes is mainly caused by the disease of the evening, and measures to combat it are, first, strict quarantine, with no seed transfer from the area; secondly, the processing of potatoes, with the whole range of potatoes, which requires cutting, and the sterilisation of knives; and thirdly, in the long term, the detection of a plant with the disease of the evening should be treated with timely spraying, with 50 per cent of the disembowelable manganese powder 1,000 times or 25 per cent of the rhesus humid powder 800 times. One in seven days and three to four in a row。
