The late sowing wheat has a short growth period before winter and the wheat seedlings are small and weak. At present, the following fertilizer and water management should be well managed for such late-seeded rice fields:
Replanting the jointing booting fertilizer in the jointing of the main stem of the field at the beginning of the jointing stage with more than three leaves and the amount of wheat per acre of wheat that meets or exceeds 350,000 should strictly control the application of jointing fertilizer. In particular, control the application of nitrogen before and after jointing. Appropriate fertilization at this time is conducive to the development of ear differentiation, but improper fertilization can make the base of the wheat seedling excessively long, causing late lodging.
Fertilization before and after jointing, mainly based on the condition of the seedlings. Before the jointing stage of wheat, the population is smaller or grows weaker, and the jointing and panicle-fertilizer can be appropriately applied early to promote the shaking of the tiller to the ear and increase the number of panicles. The wheat population is suitable and the leaf color at the jointing stage is normally faded. It can be applied once in the jointing stage or in two stages. The leaf color of wheat at the jointing stage does not fade, and fertilization should be appropriately postponed. Fields with high levels of fertility may not even be fertilized. If the seedling leaf color is younger and the seedlings are weaker at the beginning of the jointing season, the jointing and panicle-fertilizer can be applied at one time, and the urea can be topped with 10-12 kilograms per acre. Miao Wang, dark leaves can be less applied; small groups, pale leaves can be applied more. In addition to the application of nitrogen fertilizer, jointing and panicle-heading panicle fertilizer should also be properly applied with some potassium fertilizer, which is conducive to stalk plentiful, young panicle differentiation and development, and preventing occurrence of wheat lodging at later stages. Fertilizers are best used as a hole or ditch, or in the rain.
Adding foliar fertilizer in late sowing of wheat in the late growth and development, it is easy to meet the hazards of dry hot wind, it will lead to insufficient milk grain filling, premature ripening, grain weight decline, resulting in serious reduction in production, quality decline. It can use 100-150 grams of potassium dihydrogen phosphate per acre from wheat flowering stage to grain filling stage, add 75 kg of water to spray, or use high-efficiency foliar fertilizer, ash leaching solution, or spraying 0.05% aspirin solution or 0.1% chlorination. Calcium aqueous solution. Conditional irrigation of wheat yellow water once a week before the milk ripening period can reduce the harm of dry hot wind, promote grouting of strong seeds, and increase yield and quality.
Studies have found that mushroom foods, such as Agaricus blazei and Algae mushroom, contain a variety of active polysaccharides. These polysaccharides have anti-cancer activity and are helpful to the human body in preventing cancer. However, He Jiguo reminded that people should not rely too much on these things to fight cancer. After all, these substances are very low in content.
