On June 15th, when the reporter interviewed Jintangwan Village, Wupeng Township, Yilong County, Sichuan Province, Zhao Wenjun, the stationmaster of the Agricultural Technology Station of the County Agriculture and Animal Husbandry Bureau, was presenting the melon farmers to explain the safety of the greenhouse. technology. The scientific management of the hot season is related to the yield of watermelon in the later stage. In order to ensure the healthy growth of watermelon in summer, Zhao Wenjun gave three tips to melon farmers:
First, improve the growing environment
Strengthening ventilation can reduce the temperature and humidity in the shed, which is conducive to the control of diseases; the temperature of the shed is controlled below 35 degrees. After the first squash is harvested, some of the densely planted watermelons can be properly removed. Properly pruning, reasonable control of the number of melons, in order to reduce nutrient loss, increase the light-receiving area, protect the rattan leaves, ensure the safety of watermelons in summer, improve yield and quality.
Ditch drainage and flood control. In the hot season, there is often heavy rainfall, which can deepen the ditch and add water pump drainage to prevent rainwater from pouring into the greenhouse. The roots of the watermelon are soaked in water and cause the roots to die or the watermelon to crack.
Second, nutrition supply
Fertilize. In the hot season, watermelons grow fast, and the nutrients are comprehensive and easy to absorb quickly. It is difficult to meet the demand of watermelon for rapid absorption of whole nutrients in the simple use of compound fertilizer. Therefore, watermelon is applied in the hot season, and the water-soluble watermelon is quickly absorbed and contains 10 kinds of nutrients. Cuikang Chong Fertilization 500～750g+ç¿ åº·ä¿ƒæ ¹æ¶²400 g / mu as a top dressing with water, once every 10 days, to meet the needs of watermelon birth. At the same time, in order to adjust the soil structure, prevent soil compaction, improve fertilizer utilization, and delay root aging, each batch of melon can be applied once more to the seaweed fertilizer (5 kg / mu), which is conducive to maintaining the growth of watermelon to prevent premature aging.
Potassium and magnesium to prevent premature aging. In the high temperature season in summer, watermelon is prone to yellowing of old leaves, symptoms of potassium deficiency and potassium deficiency, and short leaf life and rapid premature aging, which seriously affects the later yield. 10 to 15 kg of potassium and magnesium sulfate are applied together with top dressing, and supplemented with Cui Kang Baoli 100 g/mu foliar spray, once every 7 to 10 days;
Add trace elements such as boron and zinc. During the melon, spray 1 or 2 times with 1500 times of Cuikang Jinpeng Liquid to effectively prevent deformed melons and hollow melons; expand the period (egg size) with Cui Kang Shengli Liquid 6 times + Cui Kang Bao Li (or Cui Kang Jin Potassium) 700 Spray 1 or 2 times to effectively prevent watermelon white or yellow heart, reduce thick skin melon, improve watermelon quality, and delay premature aging.
Restore the growth. It is a serious melon garden for the decline of vines; 500 grams of Cuikang high-nitrogen rushing fertilizer + 300g/mu drip irrigation for 2 to 3 times (including 10 kg/mu of Saide seaweed fertilizer) can be quickly restored. Growth and delay root aging.
Third, pest control
Powdery mildew: high humidity and heavy onset. The rainy and sunny alternate weather is heavy. Control agents can be used: 50% Tribe 3000 times liquid or 43% good Lectra 5000 times liquid, 10% Shigao (Smart) 1500 times liquid spray, the water spray volume is large (mu water consumption is above 75 kg), the leaves and vines are even Spray through.
Bacterial wilt: manifested as cracked vines and red mud. Control points: Strengthen ventilation to reduce humidity, and timely use drugs to protect the wound.
Patio Cooling
Misting systems have been used in outdoor cooling applications for decades. These systems can provide outdoor cooling reducing temperatures by up to 40 degrees Fahrenheit with virtually no noticeable increase in the relative humidity. Applications for outdoor misting systems include restaurants, theme parks, hotels and resorts, arenas, tennis courts, golf facilities, fountains, waterfalls, patios, and more.
At 1000 PSI, water droplets as small as 5 microns (5 millionths of a meter) in diameter can be produced. At this level, `flash evaporation` occurs reducing the ambient temperature. This process of `Thermal Dynamics` is effective because water requires energy (600 calories of heat to evaporate 1 gram of water) to evaporate. This energy exchange results outdoor cooling, or reduced temperatures.
Outdoor Cooling
As with any outdoor cooling system, the overall effectiveness of the mist system will depend on existing temperature, the humidity levels, and the air exchange rate. With high temperatures (above 80 degrees Fahrenheit) and low humidity levels (below 50%) the mist system results can be dramatic especially when there is constant air exchange within the patio. Fresh incoming air is quickly cooled without causing an uncomfortable increase in humidity levels. As with any evaporative cooling process, the more moisture evaporated, the greater the systems outdoor cooling capability.
The new Revolution Series by botuois the latest innovation in climate control and is ideal for evaporative cooling and outdoor cooling applications. Because of the unique design of this unit, it can be used for both indoor and outdoor applications.
