Improve lighting conditions Protected cultivation of melon should be covered with a drip-free membrane and keep the membrane clean. Try to obtain the maximum light transmittance and allow the soil to accumulate more heat. Reducing strains, suitable for sparse planting, attention to pruning, vine-tanning, and topping, to fully improve field lighting conditions.
The temperature difference between day and night during the melon-expanding control period of melons is large, which is conducive to the accumulation of nutrients during the day and the reduction of night consumption. The daytime temperature during sunny days should be controlled at 26°C to 28°C, and the nighttime temperature should be controlled at 10°C to 12°C. In the event of unusual weather, remedial measures must be taken promptly.
Scientific management of fertilizer and water should be applied to organic fertilizer, in particular, more fully cooked and harmless treatment of chicken manure and cake fertilizer and other high-quality organic fertilizer, do not use too much nitrogen fertilizer. Reasonably water, keep the soil with enough water, water a few times, it is not easy to water in rainy days, it is better to water in sunny morning.
Retain the appropriate melon section Do not leave root melon, usually more bitterness on the root melon, because the root melon is close to the root of the plant, the effective function of the leaves is less, the nutritional condition is poor, if the fruit development is in the low temperature period, the lack of light and malnutrition Under the circumstances, it is easy to make melons thick and bitter, but sitting melons can not be too far away from the roots.
Do not injure the roots when planting in time. During planting and field management, do not injure roots or minimize root damage. Avoid bitterness.
The correct application of cultivating melon during the appropriate period of harvest, with sitting guayan 5 grams per 5 grams of watered (diluted 400 to 600 times), the application of the concentration and the ambient temperature, high temperature concentration should be reduced; the temperature is lower than 15 °C should not be applied. After sitting on the melon, it must be harvested after the melon has fully matured to fully convert the bittersin. It is recommended to reduce the administration of guarana or plant growth regulators.
If grafted and cultivated, we must pay attention to the selection of rootstock varieties. Strengthen pest control. The diseases and insect pests in summer corn ear should focus on the control of brown spot and corn borer. Brown spot can be treated with 12.5% ​​wolfberry fruit leaf or 12.5% ​​trifenin foliar spray; corn glutinous rice can be brewed with phoxim granules in large bell mouth or with 4.5% beta cypermethrin emulsion or 50% phoximidine cream Heart leaf spray for prevention and treatment.
Cosmetics are compound mixtures made of various raw materials through reasonable deployment and processing. Cosmetics have a wide variety of raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: matrix raw materials and auxiliary raw materials.
The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetic formulations and plays a major functional role in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other properties to cosmetics, which are not used in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production procedures such as heating, stirring and emulsification.
