First, the facility
1. The cultivation trough has a 80cm walkway in the north of the greenhouse, and 30cm in the south. The brick is used to form a north-south cultivation trough. The inner diameter of the trough is 48cm, the trough height is 24cm, and the trough is 72cm. It is also possible to directly dig a semi-underground cultivation trough with a width of 48cm. , 12cm deep, and two layers of bricks on both sides. A 0.1 mm thick plastic film was placed in the groove, and the film was pressed on both sides with the uppermost brick. A 3cm thick clean river sand is laid on the membrane, and a layer of woven bag is laid on the sand, and the substrate is filled on the bag.
2. The water supply equipment uses metal pipes for tap water supply pipes with tap water or water level difference of more than 1.5 meters, and the plastic pipes are used for the main pipes in the greenhouse and the drip irrigation belts in the cultivation tanks. 1 to 2 drip irrigation belts are placed in the tank, and a 0.1 mm thick plastic film is coated on the drip irrigation belt to prevent dripping water from being sprayed.
3. The raw material for cultivating the matrix organic substrate can be corn stalk, mushroom slag, sawdust, etc. Before use, the substrate is sprayed with a wet cover film for 10 to 15 days to be sterilized and disinfected, and a certain amount of inorganic substances such as sand and slag are added. In the cubic rice matrix, 2 kg of organic soil-free cultivation special fertilizer and 10 kg of chicken manure are added. After mixing, the tank can be filled. After each crop is harvested or the substrate is disinfected, the substrate is generally updated once every 3 to 5 years.
Second, before the planting and planting, the substrate is thoroughly leveled, and the substrate in each cultivation tank is flooded with large water to make the substrate fully absorb water. Two rows were planted per tank after water infiltration, and the matrix was slightly higher than the base of the stem. Plant spacing of 45cm, 2000 plants per 1 / 15 hectares (1 mu), lightly poured small water after planting.
Third, management
1. Fertilizer management generally waters 1 to 7 days after planting, keeps the rhizosphere moist, and makes the zucchini grow moderately. After fruit setting, it will be poured once a day in the morning and afternoon. If it is cloudy, it may be less or not poured. Generally, it starts 20 days after planting, and then topdresses once every 10 days, each time 15 grams of special fertilizer is applied to each plant, 25 grams per plant after fruit setting. Spread the fertilizer evenly 5cm away from the root, and apply carbon dioxide gas fertilizer as needed in the greenhouse.
2. After temperature and light management are fixed, the temperature is maintained at 20-25 °C during the day and around 12 °C at night. After sitting on the melon, keep 25 to 28 ° C during the day and 12 to 15 ° C during the night. The zucchini is warm and hi-light, and the grass should be laid early and the plants should be seen as much as possible.
3. After the plant is adjusted for root melon harvesting, use plastic rope to hang the vine, and remove the side buds, tendrils and old leaves in time to facilitate ventilation and reduce nutrient consumption.
4, artificial pollination and hormone treatment early 6 ~ 9 hours to remove male flowers, the anthers gently applied to the stigma of the female medicine, 1 male flower to give 2 to 3 female flowers. Apply the stalk and stigma with 20 to 30 μl/L of anti-falling pigment at around 10 o'clock.
5, 50 days after harvesting, the root can be seated, the weight of about 250 grams can be harvested. After the 500 grams of zucchini will be harvested and listed.
