Zucchini organic soilless cultivation method

I. Facilities 1. Cultivation trough 80cm walkway in the north of the greenhouse and 30cm in the south. Use a brick barrier to form a north-south cultivation trough. The trough has an inner diameter of 48cm, a trough height of 24cm and a trough distance of 72cm. It can also be used to dig semi-submerged cultivation troughs directly. Groove width 48cm, depth 12cm, two sides and then use two brick barrier. A 0.1 mm thick plastic film is laid in the tank and pressed on both sides with the uppermost brick. A 3cm thick clean river sand was laid on the membrane, a layer of woven bags was laid on the sand, and the cultivation substrate was placed on the bags. 2. The water supply equipment uses tap water or water tanks with a water level difference of 1.5 meters or more to supply metal pipes for external pipes, and the main pipes in greenhouses and drip irrigation belts in the cultivation tanks all use plastic pipes. 1 to 2 drip irrigation belts are installed in the tank, and a thin plastic film 0.1 mm thick is coated on the drip irrigation belt to prevent drip irrigation from spraying. 3. The raw materials used to cultivate the matrix organic matrix can be corn stalks, mushroom slags, saws, etc., before use, the substrate is first wetted with a cover membrane for 10 to 15 days for sterilization, and a certain amount of inorganic substances such as sand and slag are added. One cubic meter of matrix is ​​then added with 2 kg of organic soilless cultivation special fertilizer and 10 kg of chicken manure. After mixing, it can be filled with troughs. After each crop is harvested or the substrate is disinfected, the matrix is ​​generally updated 3 to 5 years. Second, before planting and colonization, the substrate shall be leveled and leveled, and the matrix in each cultivation tank shall be flooded with water so that the matrix can absorb water sufficiently. After water infiltration, 2 rows were planted in each trough, and the substrate was slightly higher than the base of seedling shoots. Plant spacing is 45cm, 2000 plants are planted per 1/15 hectare (1 acre), and light water is poured after planting. III. Management 1. Fertilizer management Generally, 5 to 7 days after planting, 1 water is poured to keep the matrix of the rhizosphere moist, so that the zucchini grows moderately. After the fruit set, it is sunny in the afternoon and 1 in the afternoon. The cloudy condition can be given less or not. Pouring; topdressing generally starts 20 days after planting, and then topdressing once every 10 days. Each time, 15 grams of special fertilizer is applied to each plant, 25 grams per plant per fruit. Spread the fertilizer evenly 5cm away from the root. In the greenhouse, you can apply carbon dioxide gas fertilizer as required. 2, temperature, light management after planting, the temperature is maintained during the day 20 ~ 25 °C, about 12 °C at night. After sitting in the melon, keep it at 25-28°C during the day and 12-15°C at night. Zucchini thermophilia, hi light, should be early to pull the grass and grasshoppers, as far as possible to see more light plants. 3. After the roots of the plants are harvested and harvested, the vines are hung with plastic ropes, and lateral buds, tendrils and sick old leaves are promptly removed to facilitate ventilation and reduce nutrient consumption. 4, artificial pollination and hormone treatment as early as 6 to 9 male flowers, the anthers gently coated in female stigma, 1 male flower grant 2 to 3 female flowers. At about 10 o'clock, the stalks and stigmas were smeared with 20 to 30 microliters/liter of anti-drops. 5. About 50 days after harvesting and planting, the root melon can sit and live, weighing about 250 grams can be harvested and listed. After the size of about 500 grams of zucchini can be harvested and listed.
