Production technology of loofah in greenhouse

First, the soil preparation is arranged with a drop ratio of 0.2ml / 0.3, ridged and watered after ploughing, and further leveled when the humidity is suitable.

Second, fertilize 10 cubic meters of soil fertilizer (chicken and duck manure, etc.) per mu, 500 kg of bio-organic fertilizer, 50-60 kg of compound fertilizer with 15-15-15 content of nitrogen, phosphorus and potassium, and 20-25 kg of trace elements.

Third, ridging 140 centimeters between the two ridges is the most suitable. Planted in the lower half or lower part of the gully slope, that is, the planting behavior ditch, the bottom of the ditch is 35-45 cm wide.

Fourth, planting according to the row spacing of 40-50 cm, plant spacing of about 25 cm to dig holes. It should be planted in sunny weather in recent days. Do not pinch the base of the stem when pulling seedlings, so as to avoid excessive injury to the stem epidermis. Gently put the pulled seedlings into the dug hole and gently bury the soil to prevent damage to the stem. Do not take too long to plant, watering in time after completion, pay attention to control the temperature, about 30 degrees during the day, 19 degrees at night, to ensure that the whole seedling is strong.

5. Cover and hang the seedlings with suitable length of clockwork or bamboo slices in the planting line, each arched at an interval of 60-80 cm, connect a piece with a rope from the top, then cover the top of the seedling with plastic film, open a hole of suitable size on the top of the seedling, let the seedling expose above the film, and press both sides.

6. leaving the first melon first depends on the growth of melon seedlings. Generally, when planted in late September, early October or late February, the air temperature and ground temperature are relatively suitable and the growth is exuberant. At this time, you can leave the melon head in 15-18 leaves (the height is 150-160 cm after the head, it is convenient to manage) New Year's Day before and after planting, the general temperature is relatively low, the growth is weak, leaving melons can not grow commercial fruit, can only be postponed, can be left in 20-30 leaves to start.

7. Timely watering and reasonable fertilization, especially in winter watering, it is also chosen to be carried out on sunny days in recent days, and the interval is uncertain. When the air temperature and ground temperature rises from May to September, we can use flood irrigation, once every 7-10 days.

Timely picking according to customer demand and price, generally 50-60 cm in length and 3-5 cm in diameter can be picked. Pick it in the morning, pick it when the temperature in the shed rises, and cover it with a wet cloth in a cool place, so that it can withstand storage and transportation and avoid dried flowers for packing or framing for sale.

Packing generally customers like to pack them in foam boxes and ship them to their destination at once. From November to April, plastic wrap can be added to the box, and ice can be added to the box according to the needs of customers in the high temperature season from May to October. Hu Naiyi
