Winter melon is a vegetable that many farmers can often eat. It is mainly distributed in other tropical and subtropical regions of Asia, and is cultivated in various parts of China. There are wild species in southern Yunnan, but the fruits and vegetables are very small. Generally, there are more melons selling green skin in the market. If there is less black skin, then we will talk about how the black melon is planted. One: environmental conditions According to professional growers, winter melon prefers a warm environment and is a kind of heat-resistant crop. Therefore, in order to be able to grow well, it should be planted under conditions of good weather and humidity. If the air is dry, the temperature will be Low, or rainy days, insects have less activity, which is very detrimental to pollination. For example, because Hainan has a temperature of more than 20 degrees in winter and spring, the sun is still relatively good, so it can be planted throughout the spring and winter. Two: sowing If you plant melon in spring, it will be affected by low temperature. It is a very good choice to choose nutrient mash for nursery. The nutrient soil needs to be prepared in advance. It can be screened with fertile soil, mixed with decomposed livestock manure and chaff ash. Make it, add a little NPK compound fertilizer, but also pay attention to the need to fine and then mix, otherwise it is easy to hurt the root. In addition, it should be noted that the melon seeds need to be soaked in 55 degrees of warm water for about fifteen minutes, and still need constant stirring, then soaked in normal temperature water for 12 hours, soaked and then placed under conditions of 30 degrees to germination. Generally, it will germinate after soaking for one or two days. If the seed skin is smooth and rib-free, it is because the permeability is relatively poor. When germination, it may be rotted due to lack of oxygen, and the germination rate is low. Therefore, this type of seed needs to be washed with fine sand first. Remove the sticky material and place it under the environment of 30 degrees to promote germination. Before germination, you need to wash the seeds with clean water every morning and evening, and then drain the water in time to continue germination. The nutrient soil should be thoroughly irrigated one day before sowing. The depth of sowing is generally chosen to be between 2-3 cm. 1-2 seeds of germinated seeds are planted in the sputum, and the seeds are either flat or the buds need to face upwards. Cover the sunshade net after sowing. If you encounter a cold wave or a rainy day, you should pay attention to cover it with a film. It is necessary to pay attention to watering between sowing and emergence, but not too much, afraid of rotten roots, as long as the soil is moist. When the seedling rate reaches 70%, it is necessary to remove the cover. Before the seedlings are broken, it is necessary to properly control the water. After breaking the heart, it is necessary to maintain the semi-dry and semi-wet of the soil, so that the seedlings can grow stronger. It takes about a month to transplant to the field. Two or three days before planting, you can first use the chlorothalonil to drench the seedlings, so that you can take the medicine with fertilizer transplant. Three: soil preparation and fertilization The root system of winter melon is generally developed, and the growth period is relatively long. In order to increase the yield, it is very good to choose the sandy loam with rich soil and deep organic matter. In order to avoid the cold wave during the seedling period, the drainage from the north to the south is good. In the field, if you choose a good field, you need to carry out deep ploughing. The depth selection is more suitable at 30 cm. Winter melon has strong nutrient absorption ability, so it is necessary to apply it to the base fertilizer. This is also the basic condition for the growth of winter melon seedlings. The base fertilizer is best applied to the farmyard manure plus bean cake plus potassium perphosphate, and then mixed into the soil. Then planted. Four: Management In order to ensure high yield and stable yield, it is necessary to provide better conditions for melon, to make winter melon better growth and development, to alleviate the cold, dry rain, rain and pests, etc. In the process of planting, adopting the mulching film to cover the winter melon, it will directly increase the yield than the open field. About thirty-five percent. The use of a white film is most suitable, because weeds are also very easy to produce, so we need to spray a herbicide before the cover film and then cover. In addition, before the film is covered, the ground should be flattened, the fine soil should be applied, and the base fertilizer should be applied to keep the soil moist. The cover film must be flattened and pressed against the edge film. After the film is covered, the root water should be poured, and then the mouth should be sealed with fine soil. Be careful not to let the humidity inside be too large or not, as long as it is kept moist. Generally, watering is not required for 20 days after transplanting. In the future, if there is water shortage, the method of furrow irrigation is adopted, and only half of the ditch water needs to be poured. Five: timely harvest Generally, melon needs to be stored in old melons, and the taste is also good. Generally, the melon skin will turn bright and dark green in about forty-five days after fruit setting. If the plant is green, most of the leaves are still green and not yellow. Picking in the morning on a sunny day is more appropriate. In summary, in order to increase the yield of winter melon, it is necessary to pay attention to a lot of planting techniques.
