Guofeng No.1 is a new three-line high-quality hybrid rice combination developed by the “Yongfeng Hybrid Rice Breeding Center” jointly established by Fengle Seed Co., Ltd. and the China Rice Research Institute. In 2001, it passed the examination and approval of the National Varieties Approval Committee. In 2002, it was approved by the Anhui Variety Approval Committee. In 2000, Jingle Fengle seed industry was introduced into planting in Hubei Province. It also showed the characteristics of early maturity, high yield, high quality, and multi-resistance. It also saved labor, time, and money compared to mid-season cultivation. Users generally report that: Planting Guofeng No. 1 has a small demand for nitrogen fertilizer, which can be used for less irrigation of water and less for one to two drugs. It is particularly suitable for planting in areas with insufficient water or labor, and the average yield per mu is around 550-600 kg. Can be used for wheat (oil) - melon - rice supporting varieties. First, timely planting, nurturing and growing age. The species has a shorter overall growth period and is less elastic. For a season of mid-season rice cultivation, it is generally planted in late April-early May. The seedling age is controlled at about 30 days. For one-season late rice cultivation, it is usually planted in late May, and the seedling age is controlled between 25-30 days. According to the characteristics of this variety is not strong tiller, in the time of childbirth to apply enough base fertilizer, dilute sowing, sowing, seeding per acre seeding volume requirements within 12.5 kilograms, seedlings one leaf in one heart, can spray 50-80 grams per acre 15% paclobutrazol wettable powder was used to control roots to cultivate multiple pods and strong pods, depending on the condition of the seedlings to make up the weaning fertilizer, skillfully applied to the grafted fertilizer, and transplanted the tape with soil. Second, rational close planting, insert the basic seedlings. The effective delivery time of this variety in Daejeon is shorter, and the amount of mu for use in high-yielding cultivation must be guaranteed to be 1-1.5 kg, requiring 5-88,000 basic seedlings to be inserted. Because of its high plant size and wide blade length, the variety should be cultivated in a wide and narrow manner, commonly known as "Dragon Dragons". Planting specifications: seedlings with more than two seeds per hole, 48-inch or 57-inch mid-season rice, 46-7 inches for single or double nights. Third, scientific fertilization to prevent lodging. Guofeng No. 1 needs fertilizer and medium-sized crops and is suitable for planting in fields with medium or slightly poor fertility in the Gangtian mountains. Pay attention to the combination of nitrogen, phosphorus and potassium during fertilization. Nitrogen fertilizer is mainly based on basal fertilizer. Early application of sub-fertilizers promotes early-onset, stable growth, and panicle fertilizer is prudent. It is recommended to use potassium as the main ingredient, combining with drying field and top dressing of potash fertilizer, about 10 kg per mu. Fertilizer fields can be traced to a small amount of urea, and normal fields should not be treated with nitrogenous fertilizer in the later period to prevent the growth in the middle and late periods from being too prosperous. Fourth, scientific management of water, pay attention to baking field. The water slurry management adopts shallow water transplanting, inch water activity, and shallow water moisture promotes tillering. When the number of seedlings per mu is about 150,000, the seedlings will begin to grow in the sun and the booting and flowering stages will not be short of water. Avoid water-breaking prematurely and later dry and wet-dry old rice. Fifth, comprehensive prevention and control of pests and diseases. According to local pest monitoring, timely prevention and control of pests and weeds, attention to the control of rice sheath blight.
