Scientific management of water The current late rice production has entered the booting stage. This period of time is the period when most rice needs water in its lifetime. It should maintain a certain water layer. In mid-to-late September, if the water in the field is insufficient during heading and flowering, the stems and leaves will be prematurely decayed and the photosynthetic capacity will be weakened, reducing the production and transportation of nutrients. Therefore, the field should maintain a certain water layer.
Clever application of panicle fertilizer to see the discretion of fertilizer seedlings, can be used in the 3 to 5 days before heading mu 150 g of potassium dihydrogen phosphate plus 1 kg of urea water 50 kg spray, pay attention to rain can not spray, so as not to miss.
Disease control and pest control This year, due to the rainy weather in the previous period, the late rice strips disease and the rice leaffolder were seriously damaged. At the same time, sheath blight and rice planthoppers will also enter the endangered period since September. To this end, in September, prevention and control of Rhizoctonia solani, rice planthoppers, and rice leaf roller shall be carried out. The two main prevention and control programs were carried out. The first was from August 19 to 23, with the indications of S. indica, S. pulcherrima, C. meleagris, and the treatment of bullae, rice blast, rice smut, and sheath blight. The second time was from September 1 to April 4, with the indications of Saponaria japonica, Cnaphalocrocis medinalis, rice blast, rice planthopper, and rice smut and sheath blight. We must use low-toxicity, high-efficiency pesticides, advanced application machinery, and scientific application techniques to protect the natural enemies and ecological environment of pests, reduce pesticide residues and phytotoxicity, and avoid water and non-point source pollution. Prevention and control of scutellariae japonica, sorghum mu with new farmer triazophos 150ml + Ruijinte 2 packs of water spray; prevention and control of rice leaf roller stalk swift swift kill 60ml + 60ml water spray; prevention and control of rice fly 40 grams of enemies (2 packs) or 50% of chlorfenone 150ml dilute water spray; control of rice blast, rice smut and sheath blight acres with 30 grams of charcoal (2 packs) against water spray. In addition, according to the information on diseases and pests issued by the county agricultural bureaus, the farmers should select their counterparts to prevent and control pesticides in time, but they must be careful not to use high-residue pesticides to ensure the safety of rice.
Late rice cultivation and disease prevention
In late August, the late rice production will enter the middle and late period. To ensure the late rice harvest, it is particularly important to grasp the field management of late rice in the middle and later stages.
