Greenhouse Japanese pumpkin planting technology
[Greenhouse Japanese Pumpkin Planting Technology] Japanese pumpkin is one of the preferred vegetable varieties for structural adjustment by its agricultural products because of its high quality, early maturity, strong resistance, high yield and obvious economic benefits. In recent years, the cultivation area of ​​Japanese pumpkins has become larger and larger, and the cultivation techniques of agricultural products have become increasingly urgent. In order to enable the vast agricultural products to master their cultivation techniques as soon as possible, the Japanese pumpkin cultivation techniques are briefly introduced as follows. First, the variety selection
"Gang Li", "Jin Li", "Li Zi Zi", "Yi Pin" (Taiwan variety) and other green skin pumpkin; "Orange", "Dongsheng" and other orange red skin varieties.
Second, cultivation methods
Large sheds, small arch sheds, large sheds, small sheds, small sheds, etc., covered with very early maturity, planted in February around the middle of April, planted in mid-April, double-membrane cultivation, mid-January sowing, late April and early May Colonization: cultivation of small arch sheds in the spring spring field, planted in mid-February in February, and planted in mid-March. The age is about 35 to 45 days, and it must not exceed 60 days.
Third, good breeding;
Take 70% of the superficial and fertile rice field surface soil, take 30% of the mature soil and mixed fertilizer, and mix well, add 10-15kg of decomposed chicken and duck manure per cubic meter. Finally, mix 40~50g carbendazim with water and smog every cubic meter, suffocate for more than one week, then load 8~10cm nutrient mash and set aside. Seeds should be placed in warm water of 50～55°C, boiled for 10min while stirring, and then dipped to 35°C for 4~6 days. Pick up the towel for the mucus and wrap it in pure cotton cloth at 28～30°C. Under the germination. When the bud grows to 3~4mm, it can be sown in the nutrient bowl, poured into the bottom water, covered with plastic film, and kept warm and moisturized to facilitate emergence. When 1/3 is sprouted, the film is removed in time to prevent the occurrence of long seedlings. The temperature of the seedbed is 25 to 30 °C before emergence, and 25 °C during the day after emergence and 15 °C at night. After emergence, sunny days should be as much as possible to see the light, rainy days should be based on heat preservation, but in the case of continuous rain and snow, moderate ventilation. Try not to water the seedlings, but the nutrients and topsoil should be watered. Before watering, put the water into the preheating beforehand. When the melon seedlings are 2 to 3 true leaves, the plant height is 10 cm, and the seedling age is 34 to 45 days, colonization is carried out.
4. Fertilization, sputum and colonization
The base fertilizer is mainly organic fertilizer, 2～3 cubic meters/667 square meters, imported ternary compound fertilizer 20kg, potassium chloride 15kg, urea 5kg, 畦6～8m, 2 rows per plant, plant spacing 40～50cm, cross Planting, 350 to 400 plants per 667 square meters (implementing a single vine), such as 300 plants, the implementation of double vines or three vines. When planting, the seedlings of the seedlings should be slightly higher than the noodles, and the mulch should be straightened and flattened.
V. Field management
After the pumpkin is planted, the arch shed should be closed within one week, and the moisturizing and moisturizing should be promoted. After the seedlings survive, the film should be gradually opened, and the light should be increased as much as possible. The rainy and snowy days are mainly heat preservation. If it encounters 7 to 10 days of continuous rainy days, the same must be done. Appropriately uncover the membrane ventilation. The temperature of the greenhouse should be 25~30°C during the day and 15°C at night. As the temperature rises, it is necessary to prepare for high temperature. For the cultivation of the arch shed, the two sides should be ventilated when cooling down. If you are too long, you should pay attention to the middle ventilation. When the shed is closed at 3 pm, it can be maintained until the end of April. Early-maturing cultivation and cultivation of pumpkin is usually carried out during low temperature and short sunshine. Therefore, the early male flowers are rarely or poorly developed. At this time, the female flowers can be spread with the 1:5 concentration of the squash, which promotes the fruit setting. After the male flowers develop normally, the pumpkins should be carried out. Artificially assisted pollination should be carried out before 9 o'clock in the morning. After pollination, in order to prevent rain, the leaves can be covered to cover the female flowers. The field is equipped with ditches and can not accumulate water. In order to ensure the high quality and high yield of pumpkin, it is necessary to pick the root melon early, usually in the 17 to 20 hours after pollination. In order to prevent the occurrence of powdery mildew, carbendazim, chlorothalonil, thiophanate and other sprays can be used to prevent disease. In late June, Japanese pumpkin cultivation basically ended. Generally, the output per 667 square meters is about 1000-1500kg.
