Detailed Explanation of the Key Points of Rice Dry Seedbed Seedling Cultivation Technology
In recent years, the performance of dry seedbed seedling cultivation and field transplanting by our city's agricultural technology extension center in various townships shows that the rice dry seedbed seedling cultivation technology has the effects of saving labor, saving field, saving water, saving expenditure, being easy to operate, and significantly increasing yield. The main reason for the yield increase is making full use

Detailed Explanation of Cultivation Points for the Late Growth Stage of Rice
Pest and disease control: Diseases: The main disease requiring attention in the late growth stage of rice is rice blast. After rice heading, seize the opportunity to apply pesticide 2---3 times, with an interval of about 7 days. Apply about 100 grams of tricyclazole wettable powder per mu, mixed with 30 kg of water for foliar spraying.

Five preventive management measures for the late growth stage of rice
When rice enters the late reproductive stage, it is a critical time for yield formation, and the following five preventive measures must be carried out well. 1. Prevent fertilizer deficiency. For fields where no nitrogen fertilizer was applied at the mid stage and where fertilizer deficiency and premature aging appear at the late stage, 2-3 kg of urea per mu can be applied at the booting stage as a booting fertilizer. For those growing normally and robustly,

Preventing lodging, premature senescence and delayed maturity in rice during the late growth stage
Abnormal phenomena in rice such as lodging, premature senescence and delayed maturity are caused by improper selection of varieties or by the influence of certain adverse factors during the growth and development of rice, resulting in conditions inconsistent with the normal growth targeted by cultivation, and seriously affecting the yield and quality of rice

How to prevent and control rice purple sheath disease? Practical methods and key technical points
Symptoms After rice heading, dense pinhead-sized purple dots appear on the leaf sheath of the flag leaf, then gradually spread to most of the leaf sheath or the entire leaf sheath turns purplish-brown, especially obvious on the outer wall of the leaf sheath, sometimes infecting the inner wall or reaching deep into the stem. In severe cases, the flag leaf dies 7-10 days early.

What are the control methods for rice stem borers?
Netizen Yeshan Judicial Office sent an email on July 4: I am a staff member of the town agricultural technology station. Right now we have too many rice stem borers here, and they are hard to control! I had farmers use Dakuangsha and dimethoate, but the feedback was that the control effect on stem borers was poor. May I ask what methods should be used to control them

Key Technical Points for Field Management of Rice During the Green-Returning and Tillering Stage
The green-returning and tillering stage of rice refers to the period from transplanting to the time before jointing and booting. This period is important for determining the number of panicles and laying the foundation for panicle and grain development. The main goal of field management is to promote good root development, rapid green-returning, and early tillering, and to form sufficiently strong

Field Management Techniques for Rice During the Jointing and Panicle Elongation Stage
Rice jointing begins around the peak tillering stage and internode elongation does not stop until several days after heading; in production, this period is called the jointing and panicle elongation stage. The field management goals during the jointing and panicle elongation stage are: on the basis of preserving tillers and increasing panicles, promote strong stems and large panicles, and prevent excessive vegetative growth

Detailed Explanation of Rice Super-High-Yield Intensive Cultivation Technology
I. Technical Characteristics Compared with traditional high-yield cultivation techniques, the rice super-high-yield intensive cultivation technology system has the following characteristics. 1. Early transplanting of young seedlings. The intensive cultivation technology allows transplanting of 2-3 leaf-age seedlings in winter fallow fields or winter paddy fields, and 3-5 leaf-age seedlings in double-cropping fields

Control Methods for the Small Brown Planthopper at the Rice Heading Stage
The small brown planthopper (Laodelphax striatellus) not only transmits viruses that cause rice viral diseases such as rice stripe virus disease, but also congregates on the panicles to cause damage during the heading stage of late rice. To clarify the control efficacy of pymetrozine and other pesticides against the small brown planthopper at the heading stage of late rice and the application techniques, Cheng Qinhai and others from the Plant Protection Station of Haining City, Zhejiang Province, conducted field
