Qiuqiu gourd can be listed at the beginning of September, the harvest period can be extended to the end of October, just fall season. Its high yield cultivation techniques are as follows:
Select land preparation and apply base fertilizer. Before the selection, no melons were planted, and loam or sandy loam soil with low water level and convenient drainage and irrigation was selected. When the soil moisture is suitable, deep plowing the soil 25-30 centimeters, squeezing finely; leveling ditch 1.4 meters, width 40 centimeters, depth 25 centimeters; per acre ditch decomposed chicken manure, pig manure and other high quality farmhouse 3000 kg of fertilizer, 25 kg of NPK fertilizer, and 2 kg of biological fertilizer; mix evenly and then cover the soil and wrap ridges; achieve fertilizer grooving in the center of the ridge, with a ridge width of 0.8 m and a central ridge height 15 cm, slightly lower on both sides. Then, lay the film and prepare it for broadcast.
Use fine varieties and fine sowing. Autumn zucchini selects early maturing, short vine, heat and disease resistant varieties. Press a large row of 1.2 meters, a small row of 60 centimeters, 45 centimeters in the hole in the membrane, put the seeds in every two, and then covered with wet fine soil.
Field management. 1. Dingmiao: When the seedlings grow to 1 - 2 true leaves, according to the principle of leaving strong to weak, leaving a plant per mu, left 1650 acres of left and right.
2. Fertilizer and water management: When there is a lot of rain, pay attention to exclude water from the field in time after the rain. Due to the use of plastic film covering cultivation, it is generally not easy to drought, such as drought should be poured in a timely manner, in order to promote root development and enhance disease resistance. After the melons have been harvested, they are sprayed once every 7-10 days to supplement nutrients and increase yield.
3. Falling and falling fruit: Summer squash is a cross-pollination crop of insect-like flowers. When autumn sorghum is cultivated, there are more pollinators, and once squash is seeded, if it is long and small, yield and commodity value will be reduced. If you encounter even rainy weather, it is easy to drop flowers and fruits. Therefore, 2,4-D flowering should be adopted to effectively prevent falling flowers and increase the value of the goods. The method is to spray the stigma of the newly opened female flower at 8 to 9 o'clock in the morning with a concentration of 20-30 mg/kg of 2,4-D aqueous solution.
4. Timely harvest: single melon weight 300 - 500 grams began to pick melon, 2 - 3 days mining once.
