The fertilization of rice should vary according to varieties, regions, fertilization levels, soil characteristics, yield levels, and so on. If the same amount of rice is produced, the stem wheat needs more potassium than the japonica rice, the late rice is more than the early rice, and the north needs more nitrogen than the south; the south needs more trace elements than the north. These factors should be considered when fertilizing.
1〠Fertilization in Putian
Cultivating strong and strong fish is the key to high yield in rice, and it is necessary to do a good job of fertilization in Putian. The application method of Proudol mineral desorption residue in Putian is as follows:
(1) Seed dressing: 100 grams of mineral debranching hormone can be used for dressing 20-25 kilograms by mixing 100 grams of mineral deproteinizing residue with 20-25 kilograms of rice seeds, and then adding appropriate amount of water and stirring thoroughly. , Strive to make the mineral depleted residue evenly adhere to the surface of rice seeds, after sowing and drying.
(2) Soaking: Use Prominent Minerals to remove 100 grams of water and add 40 kg of water to the residue, and then add appropriate amount of seed to fully submerge the seeds with water. Generally, it is soaked for 24 to 28 hours, and then the seeds are sowed or directly sowed.
Note: You can choose either seed dressing or soaking, and avoid using both methods at the same time.
(3) Weaning fertilizer: Generally, the seedlings are used from the two leaves to the three-leaf stage. The method uses 100 tons of mineral detoxification residue per 100 gram of water, 50 kg of water, and 200 grams of urea to be sprayed.
(4) Strong seedling fertilizer: It should be applied three days before transplanting. The method is to use 100 mg of water and 50 kg of urea and 200 g of urea as the foliar spray for each acre.
2, field fertilization
(1) Sticking roots: Use "Proud Green" brand minerals to remove residual elements 100 grams of water 30 to 40 kilograms and the right amount of fine soil and into a slurry (better with a small amount of organic fertilizer), with the stick with the seedlings can not slow down seedling.
(2) Top-dressing: The use of Pride Green Mineral Detoxification is mainly foliar spraying. The number of sprays is determined according to the length of growth period. Generally, 3 times for early rice, 4 to 5 times for middle and late rice, and the specific spraying period. And methods are as follows:
1 Fertility in the tillering period: 7 to 10 days after the transfer, the method is to use 100 grams of mineral depletion residue per acre plus 50 kg of water and 200 g of urea to spray.
2 Dial-up period fertilization: 3 to 5 days before the plunge festival, the method is to spray 100 grams of mineral residue with 500 grams of urea and 500 grams of urea per acre.
3 Heading and flowering period Fertilization: It should be carried out 3 to 5 days before heading and flowering. The method is to spray 100 grams of mineral residue with 30 grams of water and 400 grams of urea per acre.
4Fertilizing Fertilizer: It should be carried out 5 to 7 days after full panicles. The method is to use 100 grams of mineral depletion residue per acre and 30 kg of water and 200 grams of urea to spray.
Note: 1. The amount of hybrid rice is increased by 20% based on the amount of conventional rice mentioned above.
2. According to the above method, the “Pride Green†brand mineral detoxification product can be used throughout the process to effectively prevent and treat various diseases such as rice blast, bacterial leaf blight, and leaf spot disease. This will significantly reduce pesticide use and improve The quality of rice and its grain weight will increase by more than 30%.
