Xu Xin Xu Zhanguo (Guanxian Agricultural Bureau Guanfeng Seed Industry Technology Co., Ltd.) Guan County is a large agricultural county with annual wheat planting area of ​​about 1 million mu. From 2006 to 2007, in conjunction with the construction of the "Quality Wheat Variety Breeding Base" in our county, we carried out a multi-million-mu high-quality special wheat high-yielding cultivation technology demonstration project in Jiazhen, which was named Lianmai No. 18. After the inspection and acceptance by the expert group, the high-quality and high-efficiency demonstration field was 15,000 mu, the average number of ears per mu was 333,000, the average number of grains per panicle was 44.2, the grain weight was 47g, and the average yield per mu was 520.0kg, which was 380.7kg more than the average three years before the project was implemented. Increased production of 139.3kg, an increase of 36.6%. 1 Preparation before broadcast 1.1 Balanced fertilization, application of base fertilizer, fertility and fertility. Higher soil fertility can not only increase the yield but also improve the nutritional quality and processing quality of wheat. To achieve the target of 500-550kg per mu, we must base on high soil fertility and good fertilizer and water conditions, and pay attention to the maintenance of soil nutrient balance, and apply basic fertilizer in accordance with the principle of "combination of organic and inorganic materials and balance of macro and microelements." . According to statistics, the demonstration farm Mushi 4000kg of decomposed organic fertilizer, 40kg of diammonium phosphate, 15kg of urea, 10kg of potassium sulfate, 1-1.5kg of zinc sulfate, and 1.0kg of borax as the base fertilizer are applied to the bottom of the plow before cultivation. 1.2 appropriate planting. Suitable soil is the key measure for cultivating strong seedlings. The optimum soil relative water content for wheat emergence is from 75% to 80%. Poor lyricism takes various forms to ensure proper planting. 1.3 Deep plowing and improving the quality of soil preparation. Demonstration fields are replaced by rotary cultivators, cultivating depth of 23 ~ 25cm, no ploughing, cultivating and supporting, no clear dark urine, no overhead dark urn, to the Panasonic real. Breaking the bottom of the plough and expanding the amount of roots enhances the ability to store water and protect the soil. L.4 Do seed treatment. The use of wheat seed coating agent coating, no coating to take seed dressing. 40% methyl iso-sulfuric acid for controlling underground pests, seed dressing at 0.2% of the seed amount; 20% of triadimefon or oxyrhadin for prevention of total erosion, sheath blight, and seed dressing of 0.15% to 0.2%; In the case of pests and diseases, one of the above-mentioned insecticides and fungicides may be selected, and each of them may be mixed and seeded according to the above-mentioned amounts to achieve both diseases and insects. Triadimefon has an inhibitory effect on the germination of seeds and should be increased by 10% when used. 2 appropriate sowing, improve the quality of sowing 2.1 sowing specifications. According to the characteristics of Liaomai No. 18, it is required to appropriately expand the width of the loquat, preferably 2.5 to 3.0m, and the loft width no more than 40cm, in order to make full use of the ground force and light energy. The average line spacing is generally 18 to 20 cm. Liaomai No. 18 has a plant height of 70.8cm, which is short and has a wide range of potential for single ear production. It is suitable for intercropping with intercropping. The land typed with wheat, cotton, and cotton can be used in “three-twoâ€, “four-two†or “three-one†models. ", single line spacing can be properly reduced to 20 ~ 22cm. 2.2 timely sowing. Early seeding is easy to form Wang Miao, early wheat premature aging; late sowing before winter, small vegetative body, less photosynthetic products, poor root development, fewer tillers, can not form strong seedlings. Demonstration fields were planted before October 10th to achieve Miao Miao. 2.3 Determine a reasonable amount of sowing. Basic seedlings are the starting point for creating reasonable groups. Determining reasonable basic seedlings can effectively reduce control measures and reduce management costs. The high-yielding cultivation of Lianmai 18 is generally controlled at 160,000 to 170,000 plants per mu. High-fertilization lands are planted early in the appropriate period, and when the management level is higher, the lower limit is taken; otherwise, the upper limit is taken. Demonstration area acres of sowing is generally 10 ~ 12kg. 2.4 Improve the quality of sowing. At the time of sowing, we strive to achieve uniform seeding, consistent depth, loose soil cover, solid soil, and no shortage of seedlings. A Special high flow pool heat exchanger should be used instead. These heat exchangers can handle the higher secondary side flow as well as the high levels of chlorine and also have better flow characteristics making them ideal for solar pool heating or solar hot tub heating. For applications that use salt water, we recommend the Titanium version of the pool heat exchanger. This version is highly resistant to salt water and chlorine.
Our Pool Exchanger Line of heat exchangers are designed to perform at high secondary side fluid velocities with low pressure drops.
