What are the options for crop management techniques suitable for the autumn watermelon? In the autumn, watermelon must be grown in such a way that it is not suitable to use late-cut varieties. Otherwise, at low temperatures, the watermelon is not mature, which affects production and quality and reduces efficiency. 3. Whole-field application of base fertilizers and planting: whole-field fertilization is largely the same as spring planting, with two per standard sheds used for reptile cultivation. However, attention needs to be drawn to the fact that, prior to planting, due to the fact that most of the pre-plant is a melon, soil disinfection is carefully carried out, with the option of using green one as a fungicide; if the soil is dried, the water should be poured and tilled. Watering the roots and covering the roofs and sunnets of the sheds is done. 4. Field management: field management should focus on the following areas. Third, the whole branch, the taffy. When the watermelon was growing in the autumn, its branching capacity decreased, but it still needed to be carefully and in a timely manner, in the same way as the spring planting; fifth, control of the melon area and artificial pollination. In autumn, watermelon is grown with essentially the same biomass as in spring, and, except for the first female, the second or third female (the first or the second) should be artificially pollinated in a timely manner, otherwise the melon is too late (the first or the second) and its maturity is delayed, even at a low temperature, and its benefits are significantly reduced; and harvest: when the melon reaches the maturity level of the commodity, it should be collected in a timely manner. The method of determining maturity is based primarily on the seating period, but it should be noted that the same species, from flowering to maturity, take slightly longer to grow in the fall than in the spring. (2) the whole area of the watermelon must be covered under the roof of the shed by tilling, dredging, ditching, dingling, requiring drought and irrigation, drainage, gilling, 2. 5 to 3. 0 metres wide, ditching 35 cm wide, watermelon trophic ditch 50 cm wide and 40 cm deep, placing decomposed organic fats like pig manure and dung drying at 3000 kg per 667 m2 in the trophic ditch, adding 75 kg of potassium fertilizer to the nitrous phosphorus applied, fertilizers to the soil and then to the trophic ditches, and some fertilizer to be applied to the guava, such as 1,500 kg of evacuated soil per 667 m2 of fertilation, and to the soil, since the undetermined roots of the melon can absorb nutrient needs for the growth of the melon. (3) the planting of autumn watermelon shall be done at the end of august and early september, with 800 plants per 667 m2 planted on the nutrient belt, which shall be cut off from the nutrients, at a slightly deeper depth than the original soil, and shall be immediately watered, with unsensitized herbicides of the water being sprayed on the surface, i. E., 100 ml for each 667 m2 and 50 kg of water evenly sprayed on the surface. Then cover the membrane. To prevent the effects of heavy rains, the roof of the shed must be lifted immediately after planting. (4) the suitable temperature for management of watermelon growth after planting is 25-30°c, which is slow when the temperature is low; when the temperature is high, it is prone to viral disease, requiring a minimum temperature of 18°c at night and a maximum temperature of 32°c at daytime. Night temperatures were already low between the end of august and mid-september, and the night shed was closed around thin film. Every day at 8 a. M., the air was lifted and at 4 p. M. The shed was closed. Later, the temperatures are getting lower, the morning demolitions are delayed and the afternoon closure is gradually early. The chickens are usually dumped one week after planting, with both branches, and watermelons must be artificially pollinated after flowering, as there is no insect pollination in the shed. The pollination must take place between 6 and 10 a. M. It is best to choose the second female to sit on the melon, where the chicken will be squeezed with its finger so that it can be transported to the melon with the nutrients, where the melon expands to around 1 kg, where the melon is basically fixed, and where the melon is 6-7 years old, where the melon is flipped. During the field's growth, two fats (spreading chickens, fertilizing melons) were followed and water was poured twice. (5) the harvest usually takes 40 days after the watermelon is taken, which is 10 days later. Autumn watermelons are more durable and are stored at indoor temperatures for 15-20 days. • the selection of varieties, due to the short birth period of the watermelon planted in the autumn, during periods of high-temperature “volatile drought” and heavy rainfall, and the gradual decline of temperatures after the autumn, sometimes in consecutive periods, with more adverse effects. It is therefore advisable to select high-quality, high-yielding, high-temperature, strong fruit-skin, low-carrying and disease-resistant medium- and medium-prematured varieties, such as those with seeded watermelons and watermelon 12, seedless seed-free no. 3 and seedless watermelon species such as super 2011, oleg 10, spring autumn honey, century honey, etc. Ii. During the broadcasting period, three options are selected for full-scale fertilization because spring watermelon cultivation is dominated by drainage, supported by water, while autumn cultivation is dominated by water and drought resistance, taking into account drainage. Therefore, it is important to select irrigated fields for the cultivation of the autumn and to remove water stains in a timely manner. Cultivated pests are severe in the autumn and focus on prevention. Rice-producing areas are not only easy to irrigate, but also have fewer pests and are suitable for the planting of acupuncture. It has been shown that vegetable- and cotton-producing areas have a high concentration of pests, which is harmful to watermelons and more difficult to control. Due to the short birth period of the autumn watermelon, which ranges from sowing to harvesting of 70 to 80 days, it is required that the base fat be sufficiently decomposed, fast-impacted and in sufficient quantities. In order to improve production and quality, each 667 m2 can be fed 75 kg of corrosive weight, plus 50 kg of corrosive weight, or 3,000 kg of corrosive fat, plus 30 kg of corrosive fat, in combination with a full-blown cleavage to be applied to melons, while fully mixing the fertilizer with the soil.
