How to plant a light board gourd? A farmer friend who wants to grow this variety of gourd can come and study this article. This article mainly describes the high-yield cultivation techniques of light-span gourd. one. Sowing time In the northern region (Xinjiang, Inner Mongolia, Gansu), the sowing period from late April to early May, when the temperature is stable to 15 °C - 20 °C, the ground temperature can be steadily above 10 °C. Special reminder: Because the zucchini is afraid of high temperature, early planting can significantly increase the yield, and the late sowing yield will drop significantly. It should be planted as soon as possible. two.èŒ¬å£ arrangement The seed zucchini is not resistant to continuous cropping. It is prone to disease after 2-3 years, and it must be reversed. three. Land requirement Soil texture: sandy loam and loam retain water, fertilizer and permeability, and are most suitable. Formation thickness: kept above 80cm. Soil fertility: In the northern region, the soil has low organic matter, sufficient heat, proper management, and high yield and quality products. Land consolidation: deep ploughing in autumn, irrigation of water, spring sputum protection. four. Cultivation method Pingyi: The warm rainfall is even and the drainage is good. The northern sand land is especially suitable. According to the 90cm membrane, two rows, 140cm membrane, 2-3 rows of flat cultivating; seeding density of 2800-3200 per acre (row spacing 60-70cm, plant spacing 35-40cm). Advantages: labor saving and high land utilization. Disadvantages: The ground is prone to water accumulation, causing fruit to rot. 畦 : : : : : : : : : : : : : : : : : : : : : : : : : : : : : 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 Advantages: convenient drainage, good soil permeability, which is conducive to root development, and is the main cultivation method of seed zucchini. Fives. sowing Inner Mongolia, Gansu and Xinjiang regions: from late April to early May. In the seed live and sitting water live, the live broadcast depth is 2-3cm, the opening of the hole is in the shape of “tenâ€, avoiding “wearing the gunâ€, the seed is laid flat, and the wet cover is sealed after the sowing. When the soil is not good, the live water can not only restore the soil moisture but also can be released in advance. Special reminder: Before planting, use 100-150g of Zhongdingling herbicide for soil sealing treatment, planting at intervals of 6-7 days, to eliminate the use of herbicides such as trifluralin and acetochlor, otherwise it will cause seedling death. High-yield measures: sow seeding 1. After determining the overall sowing date, 10% of the total amount used for early sowing in the early season, 4-6 days in advance, to promote early results and increase yield. 2. Use 10% of the seeds to first soak the seeds with 55 ° C (2 parts boiling water, 1 part cold water) without agitation. When the water temperature drops to 30 ° C, soak for 2-3 hours, then dry the surface moisture and other seeds. Mixed seeding. six. Water and fertilizer management 1. Seed fertilizer: 15-20 kg of diammonium Phosphate and 10-15 kg of urea. 2, top dressing: raw vine period combined with watering to apply urea 5-6 kg. During the period of melon expansion, the fertilizer is applied with 15-20 kg of diammonium phosphate and 7-10 kg of urea. 3. Watering should be carried out 2-3 times during the whole growth period. 4, foliar fertilization: emergence 4-5 leaf stage, can be applied to promote fertilizer growth; fruit expansion period of application of leaf fertilizer to promote fruit expansion, increase 1000-grain weight. Apply 90% potassium dihydrogen phosphate 150 plus multi-micro fertilizer 100g, 2-3 times. Seven. pollination High-yield measures: Planting close to the source of the bee source or 15 mu of melon to ensure more than two boxes of bee colonies, effectively increasing production. Eight. Collecting seeds 1. When the water-free beads are cut, they can be harvested. 80% of the fruits are ripe, and the ripening is 15-20 days, and harvested at one time. 2, the melon seeds are cleaned, which is good for dehydration, drying and drying, the board and the dirty board are reduced, and the commodity is improved. When the dried melon seeds are reduced to 8-9%, the wind, the granules, the impurities, and the bags are stored. nine. Pest Control Prevention-oriented, integrated prevention 1. Before sowing: Avoid heavy sputum and flail; check the use of herbicides. 2, sowing period: seed coating or drug dressing. 3, seedling period: timely replanting, phoxim insect-resistant rodent birds; 5-6 leaves before the spread of the application of methyl thiophanate; after the whole seedlings flooding with alkali, relieve the phytotoxicity. 4, flowering fruiting period: after the fruit is sprayed with cyanopyrazole, stone sulfur mixture to prevent powdery mildew, 1-2 times; at the same time prevent disease and viral diseases; shallow irrigation, fertilizer sufficient. 5, fruit ripening period: spray cyanocin, stone sulfur mixture to prevent powdery mildew, 2 times; at the same time prevent disease and viral diseases; shallow irrigation, anti-water, flooding. 6, fruit harvested seeds: rotten melon timely seed; appropriate post-ripe, timely seed to prevent fruit germination; timely drying, anti-freezing plate.
