To cultivate strong seedlings, it is crucial to have good temperature and humidity. Confirm high-tech seeds and live a happy life. Tebuthiuron,Trifloxystrobin,Flufenacet,Amicarbazone,Prothioconazole,Sulfentrazone Changzhou Satidi Import and Export Co., Ltd. , https://www.guanjiejt.com
First, the soil is trimmed and the long-term vegetables are poured into the lime in 200 tons of lime per acre in the field. 15 days before planting, 100 Jinzhou Sulfur-containing Compound Fertilizer was applied, 100 Jin superphosphate and 30 Jin urea were mixed and spread as a base fertilizer. A large amount of organic fertilizer can be added under conditions and a one-time application of base fertilizer. (Insurance, save time and effort), and then plowing the fields to sit north and south as well, is conducive to photosynthesis, high ridges and ridges are not less than centimeters, in order to irrigation, drainage, ditch width 40 cm, width 1.1 meters. Just plowing the field, do not have to dig the soil, large blocks of ventilation and ventilation, cover the surface of the trench with mud digging, flat and thin and cover the film. Ninety-five percent of the vegetables must adopt the above techniques (varieties are different, and the number of species of plants is based on the packaging instructions). This can increase production by 30% and be available 15 days in advance. The nutrient soil must be made one day before and after the nutritive soil seeding is made, which is conducive to the rapid growth of seedlings and the reduction of the frequency of fertilizer application. The licensed nutrient soil method is to add 100 jin farmyard manure and appropriate amount of dry manure, plant ash, 10 pounds of compound fertilizer, 3 pounds of urea, 5 pounds of urea, and 5 pounds of calcium superphosphate in the soil where 1200 pounds are planted. With 200 pounds of water after pouring, cover film fermentation for use. According to our company's technology, it will be successful and transplanted with seedlings and soil. The operating procedure is: 5 days before the application of a small amount of organic fertilizer on the soil, sprinkle 70% of the forest with Zinc to disinfect the soil, so as to reduce the disease, and then digging, leveling, compaction of the soil, the surface of the water soaked into After the mud is leveled, the mulch is prevented from being blown and cracked by the wind. The seeds are sown at 44 cm square every other day. After covering a fine clay of one centimeter (the dry fine soil may be watered in an appropriate amount), see the small shed cover with bamboo pieces. On the film to keep warm water, promote germination (temperature above 25 degrees must be covered with thatched grass), see there are two leaves, open the shed two ventilation (seedlings must be transplanted 15-20 days). Sowing and transplanting generally do not require watering and watering. To grow strong seedlings, add 0.1% potassium dihydrogen phosphate spray to the water, virus K or virus A every 7 days to control seedling disease. This way can promote the rapid growth of seedlings, improve the uniformity and reduce the disease (forbidden use of high-strength alkali in the straw ash, easy to rot with dead roots, a waste of time). Diseases and pests control vegetables to prevent disease, it can not speak. One of the main diseases of corn was smut, and it was found that 2 tumors were eradicated in time, and that the small spot was sprayed with 50% carbendazim 600-800 times solution and 50% thiophanate-methyl 500 times solution. 3 stem rot, breeding disease-resistant species is the key, close planting, not too close; the use of formula fertilization to avoid the nitrogen fertilizer is too much, timely cleaning of the field sickness, old leaves. The main pest is corn borer, which is treated with fipronil. Use moths to protect against insects such as green worms and moths (whether using any pesticide or chemical fertilizers, the amount method must be strictly followed, and the amount of excessive economic losses is severe). People who give up time will also give up time. The messenger failed and the creditor succeeded.
Second, the seedlings are planted and transplanted when they are planted and planted. When the seedlings reach 3 hearts and 1 heart, they can be transplanted. The autumn corn and the seedlings are transplanted with 2 leaves and 1 heart. Each seedling has two rows and the spacing is 30 centimeters. When planting, use a small amount of nutrient soil to cultivate seedlings and pour water to set the roots. This will increase production by 30% and be listed 10 days in advance. After 5-7 days of colonization, the foliage was sprayed with green leaf overlord plus virus K or virus A, and about 20 days after colonization, a small amount of urea was poured on the manure, and about 5 kg of urea was used per acre. In order to increase production and enhance plant disease resistance, rare earths are indispensable. Early application of early fertilizer, a total of top dressing 3 times. The first time after springing until the jointing stage, the spring corn is the first time when it is 6-7 leaves; the second time is 14-15 leaves before the joints are extracted; after the pollination, the grain filling stage is the third time. Apply 8 kg of urea per acre. Pay attention to drainage during the rainy season, properly apply water through excessive drought, keep the soil moist, apply additional phosphorus and potassium fertilizer to autumn corn, and reapply tapping fertilizers, apply 7-8 kg of urea during jointing, promote growth, and apply ear fertilizer 35 days after sowing. Carbamate 50 kg or urea 15 kg. It is a technique to grow vegetables. Learn technology and keep it forever.
