What are the technical measures for managing summer corn during the flowering and grain-filling stage?
The main goal at this stage is to maintain roots and protect leaves, prevent premature senescence and excessive vegetative growth, extend the functional period of green leaves, prevent grain abortion, and improve seed-setting rate and grain weight. First, apply grain fertilizer skillfully: so-called skillful application should be determined by the appearance of plants in the field. In fields where ear fertilizer is sufficient, plants look good, leaf color

Methods and Technical Points for Cultivating Strong Wheat Seedlings Before Winter
Only by cultivating strong seedlings before winter can you ensure large ears, many grains, heavy grains, and a high-yield harvest for the next year's wheat. The standard for strong wheat seedlings before winter is: before winter, the main stem grows 7-8 leaves, each plant has 7-8 tillers, and 8-9 secondary roots; for ordinary wheat fields, the number of stems per mu should be

Key Technical Points for Pest and Disease Control During the Wheat Sowing Period
Grasping pest and disease control from the autumn sowing period to the seedling stage of wheat is an important technical component for ensuring full and strong seedlings. The sowing and seedling stages of wheat are also critical periods for the control of many pests, diseases, and weeds. If control is not timely, it often results in missing seedlings and broken rows, or weak and diseased seedlings. In response to the pest

Key Technical Points for Current and Late-Stage Wheat Management
In some wheat fields in our province, due to earlier drought, the secondary roots are few and short, the population is insufficient, and drought conditions still persist in some plots. In response to this situation, at the provincial spring agricultural production work conference held on April 7, Yu Zhenwen, academician of the Chinese Academy of Engineering, head of the Wheat Expert Guidance Group of the Ministry of Agriculture, and professor at Shandong Agricultural University

Key Technical Points for Pest and Disease Control During the Autumn Sowing Period of Wheat
The autumn sowing period is the foundation and key to doing a good job of wheat pest and disease control. We hope farmers will seize this favorable opportunity of autumn sowing, adopt effective measures, and carry out pest and disease control work well for soil-dwelling pests, wheat powdery mildew, and other problems, striving to eliminate wheat pests, diseases, and weeds in the bud stage.

Peanut Seed Storage Methods and Key Technical Points
First, before storage, the seeds must be thoroughly sun-dried so that the seed moisture content drops below 8%. According to experiments, when the seed moisture content is below 8%, storage is very safe, and even at -25°C, germination capacity is not affected. When the seed moisture content is above 10%, respiration increases, releasing

Technical Specification for Rice Seedling-Throwing Cultivation with Plastic Trays and Dry Raising
Variety selection According to different cropping rotations, variety characteristics and the safe full-heading stage, select high-quality, high-yield, stable-yield varieties with strong tillering ability and good stress resistance that are suitable for local planting, either balanced panicle-grain type or large-panicle type. In the riverside and southern Jiangsu areas, early-maturing late japonica rice varieties are mainly used, supplemented

Control Methods and Technical Key Points for Rice Bakanae Disease
Symptoms: After rice is infected with bakanae disease, the internodes of the affected plants elongate, growing thin and tall, the plant color is paler, the leaves are narrower than those of normal plants, there are varying numbers of adventitious roots inside or outside the leaf sheaths at the nodes, and white mold grows inside the rice stalks, later turning light red, sometimes

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.

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
