Scientific use of chemical pesticides can effectively control pests and diseases, protect farmland ecological environment, and improve rice yield and quality. In the production process, we should focus on the following tasks. The pesticide network Xiaobian is specifically introduced as follows:
1. Persist in measuring and controlling pests and diseases, and achieve prevention and treatment of drugs and timely prevention.
1 Rice aphids: 120 eggs per mu, spraying pesticides at the peak of the two eggs. 2 rice vertical leaf roller: 100 times when the leaves are small and small. 3 Rice planthopper: The amount of worms is 1500-2000 heads, and it is applied at the peak of nymphs. 4 dead leaf disease: the rickets rate reached 30%, applied at the end of rice tillering. 5 Rice blast: In the field, the rice blast disease center disease group leaves application, rice smut disease: application of pesticide protection during the rice break period.
2. Strictly control the use of high-toxicity and high-residue pesticides: It is strictly forbidden to use high-toxicity and high-residue pesticides such as 1605, methamidophos, carbofuran, inefficient phosphorus, insecticidal mites, pyrethroid, rice blast, etc. in rice producing areas. use.
3. Apply high-efficiency, low-toxic, low-residue pesticides. Through trial demonstration, a number of new pesticides with high efficiency, low toxicity and low residue conforming to the pesticide use standards of pollution-free agricultural products, such as: strong chlorinated, nocillary seed, and disease control; dry-tip nematode disease, striped leaf blight, Ruijinte, triazophos, lesben, etc. control rice aphids, leafhoppers, planthoppers and so on. Love seedlings to control sheath blight, rice smut. Tricyclazole and Fuji No. 1 control rice blast.
4. Optimize the prevention and control strategy and carry out overall prevention and treatment. China Pesticide Network recommends that while monitoring the pests and diseases and monitoring the resistance, actively adjust and optimize the chemical control technology, implement the overall prevention and treatment strategy, emphasize science, safe medication, alternate rotation of drugs, in order to achieve a multi-drug treatment, both diseases and pests Provincial labor saving, delay the purpose of resistance, grasp the important period of occurrence of major pests and diseases of rice, fight the overall battle of pests and diseases, use the small area of ​​Putian, save costs, grasp the pests of Putian, rice Honda for one or two Generation of phlegm, second and third generations of mites, three or four generations of leaf mites, planthoppers, sheath blight, rice blast, etc., organized 4-5 pests and diseases, through control, effectively control pests and diseases, thereby improving rice Yield and quality.
stone carving is a collection of creative, design, production of various works of art. Nowadays, natural stone is widely used by people, taking nature as beauty, and is used at the gate of schools, gardens and green belts, and at the gate of government agencies and units. Stone carving has a variety of design techniques, including relief, round carving, sink carving, shadow carving, engraving and openwork carving.
