1. The land to be used for loam and sandy loam should be selected, and wheat, barley, corn and leguminous crops should be suitable for the former crops, and they should not be bred or bred. Pre-winter irrigation, applying 1.5-2 tons of decomposed organic fertilizer per 667 square meters. Before the site preparation, spraying 75% Dole 150g per 667 square meters to control weeds.
2. The current cultivars are mainly selected from New Seed No.1, New Seed No.2, Lanzhou Daping, Minqin No.1 and Minqin No.2. Before seeding, 2.5% of seeds with a seed amount of 2.5% are used for seed dressing.
3. Seeding requires 10 cm of ground temperature stable at 13 °C above sowing. My group is usually conducted from May 5 to May 20, but it cannot be exceeded by the end of May. Planted with a flat membrane, spacing 40+70 cm, spacing 22 cm, seeding with 12 kg of diammonium phosphate and 3 kg of urea.
Second, field management
1. Seedlings and seedlings after sowing seedlings, seedlings in areas where there is a lack of ridges, seed sowing, replanting should not be late as soon as possible, too late to form two types of seedlings.
2. Dingmiao
2 true leaf seedlings, 4 true leaf Dingmiao, weak to stay strong, to stay strong.
3. Cultivated and weeding cultivars 3 to 4 times during the whole growth period, respectively, 7 days after sowing, seedling stage, seedling stage and vine stage. Combining the seedlings with artificial valerian.
4. Fertilizer seed vines before throwing vines combined with ditch dressing, 667 square meters of urea 25 to 30 kilograms, depth 10 to 12 centimeters. In the seedling, flowering and fruit setting stages, foliar fertilizer such as green wind 95 is sprayed, combined with foliar spray, plus 0.1% to 0.5% zinc sulfate solution, 0.02% to 0.04% manganese sulfate solution or 0.05% ~0.1% manganese chloride solution.
5. Irrigation timely and appropriate amount of irrigation dumped vines, fruit enlargement water, Gualou restore water. Require small ground irrigation, with the irrigation with the seepage, the ground does not see the clear water within two hours.
6. Pest control before sowing, sowing, seed soaking, soil treatment can prevent the occurrence of blight, anthracnose, spraying after spraying benomyl, dexamethasone, methadone, triadimefon, plant spirit emulsion control blight, anthrax, white powder Disease, virus disease. 21% eradication of emulsion 2000 times solution to prevent quails, 350 kg of oil residue, wheat bran mixed with 1 kg of dip insects in the trap around the seedlings to kill the tiger.
Third, the harvest
1. Harvest a batch of mature, harvest a batch. The melons were picked and placed for 7 to 10 days and then threshed. When using a seed melon seeder to thresh, care should be taken to prevent breakage and flowering.
2. Drying grain is dried in the cement field or color strip cloth until it is half dry and then turned. It is easy to form a rocker and reduce quality. Do not avoid rain caused by dull colors, linen patterns, water drops below 12% can be packed into the warehouse.
Containerized Oxygen Generator
ETR can combine all parts of the oxygen generation system into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks and Oxygen Generator. Even the optional oxygen booster and cylinder filling station.
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
