How to grow and manage "leaf" pumpkins? Please introduce the planting of leaf pumpkin can refer to the following methods for planting and management: first, choose the sowing time pumpkin is a temperature-loving and heat-resistant vegetable, and the suitable temperature for stem and vine growth is 18-22 ℃. Therefore, "leaf" pumpkin can choose to sow from late February to early April. 2. in order to cultivate strong stems and vines, prevent early flowering of pumpkin and increase the time of picking leaves, "leaf" pumpkin should be planted on loam or sandy loam with high content of organic matter and strong ability of sustainable fertilizer supply. Planting from the border, the width of the border is 2.5 meters, the width of the ditch is 40 cm, and the depth of the ditch is 40-50 cm. Third, reasonable close planting pumpkin is generally planted by seedling transplanting, and when the number of leaves is about 3, it is transplanted in time. "Leaf" pumpkin should be cultivated on the ground, with proper close planting, double-row planting, plant spacing of 50 cm, and about 800-1000 plants per mu. Fourth, field management 1. Reasonable introduction of vines and whole vines should be introduced frequently in the process of pumpkin growth, so that the distribution of stems and vines should be reasonable, improve ventilation and light transmittance, and reduce diseases and insect pests. The "Leaf" pumpkin was used for heart-picking and vine-pruning at 7-8 leaves, and for the second time at about 12 leaves, in order to increase the number of stems and leaves and increase the leaf yield. 2. Reasonable topdressing of "leaf use" pumpkin is mainly to harvest vegetative body. therefore, nitrogen fertilizer should be properly applied to prolong the vegetative growth period and harvest time. The main results are as follows: (1) Light application of seedling fertilizer: 20,25 piculs of mature manure water per mu or 1000 kg urea mixed with water 5 days after transplanting, in order to promote the early growth and rapid development of seedlings. The inferior seedlings should be applied more to promote the balanced growth of the whole field. (2) re-application of anti-vine fertilizer: 500kg of rotten farm manure + 20kg of urea per mu 10-12 days after transplanting, and 1000 kg of 20 kg of 30% dung and urine water per mu every 7 days after entering the picking period or 1000 kg of urea mixed with water. 3. Water management Pumpkin in case of drought and lack of fertilizer, it is easy to cause early flowering and early fruit, and the leaves become yellow and smaller. Therefore, the field of "leaf" pumpkin should be kept moist in order to promote the growth of pumpkin stems and leaves and prevent early senescence. 4. Disease and pest control (1) main diseases control: downy mildew was sprayed with 58% chlorothalonil 600x solution, 75% chlorothalonil 800x solution or 70th methyl thiophanate 800x solution; powdery mildew was sprayed with 2000 fold solution of 20% fenrucine or 750x solution of 75% chlorothalonil; epidemic disease was sprayed with 72% Kelu 800x solution or 70% mancozeb 800x solution. (2) main pest control: White whitefly was sprayed with 1000 times of 40% dimethoate EC or 1500 times of 25% aphid wettable powder, and mites were sprayed with 73% dicofol 2000 times or 20% dicofol 1000 times. Fifth, timely picking pumpkin leaves (including petiole) should be picked according to the principle of less picking in the early stage, more picking in the middle stage and less picking in the later stage. The leaves can be picked in real time when the color of the leaves becomes lighter and the leaves are thick. an appropriate amount of leaves should be retained after picking to meet the needs of plant growth. After flowering in the later stage of picking, the whole inflorescence can be picked and sold with the leaves.
