1. Water and fertilizer management. North melon is one of the melons that likes fat and has a well-developed root system. It likes moisture and cannot tolerate waterlogging. It grows quickly when there is sufficient fertilizer and water. During the entire growing period, adequate water and fertilizer should be provided. Pumpkin has a tenacious vitality and is generally grown in rural areas. If allowed to grow, it can be harvested from spring planting until frost. Therefore, sufficient base fertilizer should be applied. The base fertilizer is mainly organic fertilizer.

Second, build a frame for Beigua. If the northern melon grows creeping on the ground, it will easily form adventitious roots on moist ground, making the melon vines more likely to grow leggy. When the melon seedlings grow to about 2.5 meters, the vines are introduced and put on the shelves, and the top center of the main vines is removed at the same time. When introducing melon vines to the shelves, it is best to leave 4-6 nodes on the ground under the shelves, preparing to bury them in the soil to promote the growth of adventitious roots. At the same time, leave four branches on the main vine, and use these four branches to bloom and bear fruit. Setting up a trellis for the pumpkin can improve the ventilation and light transmission conditions of the pumpkin and increase the fruit setting rate.

Third, carry out artificial assisted pollination to increase the fruit setting rate and prevent leggy growth. Because the root system of pumpkin is developed and has a strong ability to absorb water and fertilizer, it is most likely to cause leggy growth. After sitting on the melon, the melon absorbs and stores nutrients, which can reduce the tendency of leggy growth. In some rural areas, in order to prevent the melon seedlings from growing too long, they use a knife to cut an incision lengthwise from the middle on the melon vine about 30 cm from the base. The incision should be cut in half, and a piece of cool black fresh fruit is sandwiched in the middle. charcoal. It has a certain effect on preventing excessive growth, you can learn from it. Artificial pollination is usually carried out before 10 am. Remove the male flowers that are open on the same day during pollination. Apply the anthers of male flowers evenly to the stigmas of female flowers. You can also cover the entire male flower on the female flower. If the weather forecast predicts rain in the last two days, in order to prevent the melons from turning, you can use a cover to cover the female melons that have just been pollinated. Prevent rain from washing the young melons. Covers can be used, such as pumpkin leaves, sycamore leaves or paper.

Fourth, the melon vines are rejuvenated. Generally, after picking three batches of fruits. Most of the leaves at the roots have turned yellow. In order to obtain higher yields in the future, place the northern melon seedlings that were originally prepared on the ground at the fourth to sixth nodes, avoiding the main roots, and dig a shallow pit of 5-6 centimeters below. Mix a pound of soil into it. Mix the decomposed livestock and poultry manure evenly, then bury the melon vines on top of the melon vines, cover them with 15-20 cm thick soil and pour enough water. Melon vines can produce a large number of adventitious roots. Generally, it can increase production by about 30%.
