Potato cultivation time is the best time to cultivate crops in spring from January to March. Choose sandy loam with rich organic matter for planting. Put 1500-2000 kg of organic fertilizer per mu and 150 kg of turf ash. Sprinkle the fertilizer into the field and use a rotary tiller. Mixed rake, flattening the border, border width 1.3 meters, border surface planting 3 rows, row spacing 40 cm, plant spacing 25 cm, the amount of seed per mu is 100 kg, and the mulch is covered after planting.
When the seedling emerges, the film is broken and the seedlings are introduced in time. When the wheat seedlings grow 15-20 cm, topdressing is carried out. 15-20 dan of biogas manure is used per mu, 7.5 kg of potash fertilizer is added, and the bottom of the ditch is used to cultivate the soil immediately to promote the rapid growth of the plants in the early stage. Sprinkle water often, keep the soil moist, and avoid too wet or too dry.
1. Type of selection
Select disease-resistant varieties and select healthy potatoes from disease-free fields for seeding. Firstly, pre-soak the potato seeds in warm water at 40°C-50°C for 1 minute, and then put them in 60°C warm water (the ratio of seed potatoes and warm water is 1: 4) Soak for 15 minutes. Soak the seed potatoes with 72.2% Prike or 70% Kelu (800 times liquid) for 15 minutes and then dry them for cultivation.
2. Soil disinfection
Severe soil disinfection must be carried out in the vegetable field where potato, taro, and solanaceous crops have been planted. The method is: first eradicate the stems and leaves of the previous crops, turn the soil more than 20 cm deep, and then eradicate the remaining roots (tubes) in the tillage layer to reduce pathogens. Use 50% carbendazim wettable powder 2 kg mixed quicklime 20 kg-30 kg per mu, and sprinkle 40 kg-60 kg plant ash into the field. After raking into a cultivating ridge, open a culturing hole or furrow on the top of the ridge, and sprinkle 3 kg of 40% pentachloronitrobenzene around the potato when planting potatoes and mix with 90-150 kg of dry fine soil.
3. Fertilizer and water management
Approximately 20 days in advance, add 25 kg to 50 kg of manure at 300 kg to 500 kg per acre. The ammonium bicarbonate is sealed and piled up to the sun to be fully decomposed and mixed evenly. It is applied and turned into the soil when the soil is turned deeply. When the seedlings are 3 to 5 leaves, topdressing is done once. Generally, 500 times solution of serratia vulgaris is added with urea or 1% potassium dihydrogen phosphate to add swelling element. Pay attention to strengthen field irrigation to increase the output value during the expansion of potato pieces.
Fourth, field management
1. Before emergence: The key point is to add light to avoid damage to the arch shed in wind, snow, and rain.
2. Seedling period: Those who cover up the mulch should be manually assisted to break the film in time; those who cultivate in the open field should be hoeed in time after rain or watering to break the hard shell, so that the wheat seedlings can emerge smoothly, and promote the seedlings, seedlings, and strong.
3. Growth stage: After the potato has all the seedlings, the main goal is to promote the growth of the seedlings and build a good shelf. The key to the management is not to dry or sprinkle water, and not to spread the water over the top of the ridge, and to cultivate and cultivate the soil. Finally, the square shoulder ridge is cultivated before the tuanke is sealed, and an outstanding potato-forming condition is invented. Large, medium, and small arch sheds should gradually increase the ventilation time. After the "guyu", maintenance equipment can be removed depending on the weather.
4. Potato setting period: After the potato clusters have budded, they will begin to form. In the flowering period, the potatoes will quickly expand. At this time, the amount of sprinkling should be added. The principle of sprinkling is to keep the soil moist and not form field water. During this period, we should also pay attention to the prevention and control of pests, especially potato blight, and we should take precautions in advance and take precautionary measures. Once the disease occurs, it is difficult to control. During this period, if the plants grow excessively, they need to be artificially controlled. Paclobutrazol (PP33) can be sprayed 1-2 times, and the converted concentration is 100PPm.
5. Harvest period: The watering of potatoes should be stopped 7-10 days before harvest.
â‘ Large, medium and small arched sheds are on the market early and can be sold at good prices. The suitable harvest time is around the "May Day" festival. â‘¡For the open field cultivation, it should be abundant and long enough, and the potato pieces that constitute a higher output value and a better standard can obtain better benefits. The suitable harvest time is early June.
