Technical specification for planting honey pumpkin

Sowing and raising seedlings: hole sowing can be carried out from the end of February to March, the plant spacing is about 50cm, and the row spacing is about 2m. Fertilization: apply base fertilizer after ploughing the land, ditch fertilization after plant extension, apply urea or soil fertilizer, and apply compound fertilizer or potash fertilizer at flowering and fruiting stage. Watering: sufficient water is needed after sowing and proper watering after planting. Pruning and pressing vines: the lateral branches were removed and the top was removed. Artificial pollination: after flowering, artificial pollination is carried out from 8 am to 10:00 every morning.

First, sowing and raising seedlings

1. Honey pumpkins are sown from January to March in Guangdong. If the temperature is low in early spring, cold-proof seedlings can be raised in nutrition bowls or cups, and the seedlings can be planted after the temperature warms up.

2. Hole sowing can be used directly from late February to March. Each hole can sow 2-3 seeds, the plant spacing is about 50cm, and the row spacing is about 2m. After sowing, cover a layer of 2-3cm thin soil.

II. Rational fertilization

1. Before sowing, the soil should be ploughed properly, and then base fertilizer should be applied. About 2000-3000 kg of rotten farm manure can be applied per mu.

2. After the vine extension of the plant, ditching and fertilization can be carried out about 15-20cm from the root, and about 15-20 kg of urea or 500-1000 kg of soil fertilizer can be applied per mu, which can be watered in time after applying good fertilizer, and appropriate amount of compound fertilizer or potash fertilizer can be applied in the flowering and fruiting period of the plant, and then the fertilizer can be applied reasonably according to the needs of the plant.

Third, timely watering

After sowing, in order to promote the rapid germination of seeds, sufficient water should be applied, and before emergence and planting, the amount of watering should be properly controlled, and after the planting has survived, an appropriate amount of water should be watered. Generally, it should be watered immediately after fertilization, in addition, it can also be watered in time according to the growth of the plant and climate change, the soil is not dry and irrigated, and drainage should be carried out in time in case of rainy season.

4. Pruning and pressing vine

The main results are as follows: 1. In order to improve the yield of honey pumpkin, pruning and pressing can be carried out properly, and plant pruning can be carried out by removing side branches and topping.

2. Topping method, when the plant grows 6-8 true leaves, wipe off the apical bud, retain 3-4 vines, each vine can retain 1-2 melons, remove lateral branches, retain a main vine, and all the others can be removed. At the same time, when the vine grows to 40-50cm, the vine can be pressed, and a total of 3-4 vines can be pressed.

5. Artificial pollination

After flowering, artificial pollination can be carried out at 8-10:00 every morning, the pollen will be applied on the stigma of female flowers, each male flower can pollinate 1-2 female flowers.

VI. Prevention and control of diseases and insect pests

1, honey pumpkin common pests are aphids, Huangshou melon, can choose 10% imidacloprid wettable powder 3000-1000 times liquid or 40% dimethoate 600,800 times liquid for control.

2. The main plant diseases are powdery mildew and mosaic disease. if mosaic disease is found, aphids should be controlled and eliminated in time, and then the diseased plants should be cleared in time. In order to prevent the spread of the disease, lime water can be sprayed to disinfect and control powdery mildew. Carbendazim, strychnine, colloidal sulfur and so on can be used.
