Technical points
1. Use good seed, seed potatoes virus free. The early-maturing varieties such as "Netherlands 15", "Lu Yin No. 1" and "Netherlands 7" were selected for early-maturing varieties with early potato tuber, fast tuber enlargement, short dormancy period, high yield, high quality and disease resistance.
2. Cut and germinate to ensure full seedlings. Cut germination requires about 150 kg of seeded potatoes per acre. 20 to 25 days before sowing, the seed potatoes are placed in a warm and sunny place for 2 to 3 days, and diseased potatoes and rotten potatoes are removed, and then cut into pieces. When cutting, make full use of the apical dominance, spiral to the top of the beveled, and finally according to the top bud is divided into two or divided into four, each piece of potato retains 1 ~ 2 bud eyes, weighing 25 to 30 grams. After drying the blade, put it in a room with a temperature of 18°C ​​to 20°C, and use a stratification method to accumulate germinate. When the bud grows to about 2 cm, it shall be placed under scattered light and dried.
3. Chemical seed dressing, pest control and disease prevention. Add 50 grams of prohexine 50% suspension agent and 20 ml of high-suspended 60% suspension seed coating agent into 1 litre of water and spray it onto 100 kilograms of seed potato chips. After drying, sow to prevent plant diseases and insect pests. Guarantee Miao Qi, Miao Zhuang.
4. Double or triple membrane covering, timely sowing. Generally, in the sunny days from late January to early February, single row and double row rows are planted in the large arch shed. The use of a small arch shed in a large arch shed can further mention the morning market. The ridge distance is 80 centimeters, double rows, 25 to 30 centimeters of plant spacing, and 5,500 to 6,000 plants per mu. When planting ditch deep 8 to 10 cm, 20 cm wide. Fertilizers and pesticides to prevent and control underground pests are mixed with soil. After watering, they are planted at oblique angles. The buds are upward. The buds are covered with a small amount of fine soil. Then the soil is ridiculed. The ridges are about 15 cm high and the ridges are ridged. Flat, spray herbicide, and then covered with a 90 cm wide film.
5. Soil testing formula, balanced nutrition. Adopt soil testing and formula fertilization techniques and formulate fertilization plans based on the target yield. Generally, 5000 kg of soil-fertilizer or 150 kg of commercial organic fertilizer, 180 kg of nitrogen, phosphorus, and potassium ternary compound fertilizer (15-10-20), 1.2 kg of zinc sulfate, and 1 kg of boric acid are applied per mu. Soil miscellaneous fertilizers are spread on cultivated land, and other fertilizers are applied at the time of sowing.
6. Strengthen field management. After planting, keep it at 20°C～26°C during the day and 12°C～14°C at night. The water was poured 3 times in Qimiao, Tuanshi and Leilei. When the plant height is between 40 and 50 cm, 20 ml of auxiliaries or 15 grams of paclobutrazol can be sprayed in order to prevent leggy.
7. Comprehensive prevention and control of pests and diseases. The late phase focuses on the prevention and control of late blight, starting from the beginning of the regimental period and spraying once every 7 days to control late blight. Immediately after the diseased plant was found, the diseased plant was removed, buried deep away from the field, and lime was sprayed around.
8. timely harvest, grading, packaging. Combine with the market conditions timely harvest, grading, packaging sales, increase revenue.
Precautions
According to the needs of the local market, select good virus-free varieties. When introducing, pay attention to the production conditions of the multi-breeding bases and avoid introducing diseased seed potatoes. Plastic film covering the emergence of potatoes pay attention to the timely release of seedlings to prevent injury. According to market conditions timely harvesting, if the price fluctuations are not large enough to delay harvesting and increase production.
Suitable for promotion area
Northern potato for the second season as a region.
The most common waxy and sweet corn market, waxy corn has higher nutrient content than ordinary corn, containing 70-75% starch (and almost all amylose), more than 10% protein, 4-5% fat and 2 % Of multivitamins have more grains, VA, VB1, and VB2 than rice with the highest content of protein, fat and VB2. Yellow corn also contains carotenoids, such as rice and wheat. The molecular weight of waxy corn starch is more than 10 times smaller than that of ordinary corn. The starch makes glutinous rice sticky and softer than ordinary hard corn. Its digestibility is more than 20% higher than that of ordinary corn, and it is suitable for people with irregular teeth. At the same time, the content of amylose (a kind of polysaccharide) is very high, which is not suitable for diabetics.
Waxy corn is also called sticky corn. The grains have rough, waxy endosperm, similar to shiny, transparent grains, such as hard and dented corn. Its chemical and physical properties are controlled by a recessive gene located on chromosome 9. 100% of the starch in the endosperm is amylose.
