Fine Management Techniques for Cotton at the Seedling Stage to Build a Solid Foundation for High Yield
Cotton seedling-stage management is crucial, as it directly determines whether the cotton can build a good framework for high yield and whether the reasonable transition from vegetative growth to reproductive growth can be properly adjusted. The principles of seedling-stage management are: first ensure a full stand, and on this basis cultivate strong seedlings and promote early seedling development. The key points of seedling-stage management are: check the seedlings promptly after sowing, and if rotten sprouts or rotten seeds are found, reseed in time. Thinning and final thinning: thinning can be done in two rounds. The first is after the seedlings emerge evenly, keeping strong seedlings and pulling out weak and diseased ones. The second is at the 1-2 true leaf stage, and final thinning is at the three-leaf stage, when the base of the stem has already become lignified and its ability to resist adverse environments has increased. Intertillage: through intertillage, soil temperature can be raised, water evaporation reduced, root growth promoted, strong seedlings cultivated, and early development encouraged. At the seedling stage, intertillage is generally carried out 3 times. The first is at the cotyledon stage, together with thinning. Early intertillage can raise the soil temperature around the seedling roots, promote early root development and increase absorptive capacity, so that true leaves emerge earlier and seedling stress resistance is enhanced. It can also break up soil compaction and help preserve soil moisture. The depth of this intertillage is 4-5 cm. At this time it is already June, the temperature is rising, the root system is already relatively strong, and aboveground growth is accelerating. Deep intertillage can disperse surface soil moisture, promote roots to go deeper, and control internode length, which is even more important in relatively fertile cotton fields. Fertilization: growth at the seedling stage is relatively slow, and topdressing should be based on seedling condition, applied early, lightly, or not at all. Irrigation and drainage: in single-crop cotton fields in northern cotton regions, if enough pre-sowing moisture irrigation has been applied, do not water at the seedling stage; do a good job of intertillage and moisture conservation. If watering is truly needed, then water lightly with a small amount, irrigating every other furrow, and after watering carry out intertillage to conserve moisture, improve aeration, and raise soil temperature. At the seedling stage, the suitable field capacity of the soil is 55%-70%. Disease and pest control: the main diseases and pests of cotton at this stage are cotton Fusarium and Verticillium wilt, cotton aphids, cotton bugs, cotton bollworms, cotton red spiders, and so on.

To achieve high yields in winter and spring wheat, building a solid foundation is key
Henan Province is a major wheat-producing province. In recent years, the state and the province have introduced a series of policies beneficial to farmers, supporting the development of wheat production, which has greatly improved the agricultural production conditions in our province and continuously raised the production level. The total wheat output and per-unit yield have hit record highs for 5 consecutive years. In 2007, the wheat sown area reached 75.66 million mu, and in 200...
