In mid-April, trenches are sown at a spacing of 30 cm and the depth of the trench is 6 cm. The amount per mu is 3 to 4 kg. After sowing, they were irrigated with water, and the cover soil was 2 cm thick. The upper cover film increased the temperature and kept the soil moist to facilitate emergence. When 70% of the seedlings were unearthed, the film was removed. Qi Miao to seedling height 16 cm without fertilization, every 7 to 10 days pouring a small water. After the height of the seedlings is 16 cm, 500 kg of human excrement per acre is applied in combination with watering. After appropriate growth control, prevent seedlings grow too high. After the beginning of autumn, the weather turns cold and it is the growing season of leeks. It is necessary to strengthen the management of fertilizer and water, and apply fertilizer 2 to 3 times in combination with watering. Each vine uses 15 kg of urea and 30 kg of potassium chloride. Watering is done according to weather conditions. Water is poured every 5 to 7 days during drought to keep the ground moist. The drought before the soil is frozen needs to be poured with frozen water to ensure the need after the shelter. After the beginning of autumn, it was found that the plants were convulsed and the tender pods were removed timely to promote the accumulation of nutrients in the roots.
Plant nutrients after rooting (ie, dead above the ground) buckle shed, before the shed shed, clearing the garden, smashing the surface of a layer of cooked glutinous fertilizer, the amount of 5000 kg per acre, fertilization, after the pine soil, in order to facilitate the increase in temperature. Two large sheds are buckled, two small arches are buckled in the shed, and no drip cover is used. Daytime temperature control in the 18 ~ 23 °C, night control at 8 ~ 10 °C, noon shelf temperature can not exceed 25 °C. About 45 days after the shed is harvested, the first knife is harvested. After harvesting 4 to 5 knives, it is generally not harvested and enters the rooting period. Generally about 6,000 kilograms per mu, the annual output value of 5200 yuan per mu. Leek cultivation can be harvested continuously for 4 years at a time.
Dwarf beans are selected from early maturing, low temperature resistant and disease resistant varieties, such as Jiangye 81-6, US suppliers. In mid-February the following year, dried bean seeds are directly broadcasted between the rows of leeks, with about 3,000 holes per mu, with 4 seeds per hole and 4 kg per mu. When the first pair of true leaves was unfolded and the compound leaves began to appear, a small amount of decomposed human fecal urine was applied in combination with watering, applying 500-1,000 kilograms per acre and adding 2 kilograms of superphosphate and potassium chloride. Plant buds, combined with watering per acre of human urine 2000 kg or available NPK fertilizer 15 kg. Usually the watering stage is 2 or 3 times, and the temperature and humidity pipes in the greenhouse are buried with the leeks. Outside the night when the minimum temperature stabilizes above 12°C (ie in late April), the film is removed. In order to prevent the flower from falling, it can be sprayed with 1-5 mg/l naphthalene acetic acid solution or 15 mg/l phthalic acid solution. Generally, picking is started 50 to 60 days after sowing, and picking is continued for about 40 days. Dwarf bean beans produce about 1,450 kilograms per mu with an average yield of 3,600 yuan per mu.
Luffa selection of cold-resistant, early-maturing, high-yield disease-resistant varieties, such as Jiang vegetables 1, Huaiyin early loofah and so on. In late January of the following year, greenhouse nursery seedlings will be used. When there are 3 to 4 true leaves of melon seedlings in mid-March, they will be planted on both sides of the drainage ditch in the middle of the greenhouse. One row will be planted at a distance of 1.2 meters, and about 180 plants will be planted per acre. Pour live water before transplanting. When the main gourd is 50 centimeters in length, the scaffold is introduced on the vine. Before the appearance of the first female flower, all lateral vines were removed. After the cucurbit, the vineberry melons with strong, early female flowers were selected. The rest of the lateral vines retained one leaf. After entering the melon period, attention should be paid to the introduction of vines to make them evenly distributed. The old leaves, diseased leaves, tendrils, lychees, and melon shoots should be removed in time. Timely management of melon, removal of malformed melon, plant adjustment should be carried out in the sunny afternoon. For every 1 to 2 times of fertilization, water is applied, and 15 kg of urea or 15 kg of ternary compound fertilizer is applied per acre. The two fertilizers are applied alternately, and the soil is always moist during the melon period. Early artificial artificial pollination was performed at 9-10 am on sunny days. It generally takes 10 to 12 days from the flowering of female flowers to harvesting tender melons. Harvesting melons is harvested every 1 to 2 days. Harvesting should be carried out in the morning, and the stems should be cut off with scissors. Loofahs generally produce about 3,200 kilograms per mu, with an average yield of 3,500 yuan per mu.
