A New Wheat Variety with Weak Gluten: Yangmai 13 Cultivation Technique
Yangmai 13 is a new type of weak-gluten wheat cultivar developed by Jiangsu Institute of Agricultural Sciences under the Lixiahe River. The ripening period is about 1-2 days earlier than that of Yangmai 158. It is spring-grown with seedlings standing upright and growing at a height of 85 cm. Stems are stout, with big spikes and large grains. Generally, the effective ear number is about 280,000 per mu. The number of solid grains per panicle is 40-42, the grain weight is 40 grams, and the bulk density is 800 grams per litre. Long awn, white shell, red grain, silty, fast grain filling, good ripening, medium tillering power, high spike rate, high resistance to powdery mildew, light sheath blight, cold resistance, good moisture resistance, resistance to fat, The yield per mu is about 340 kg. It is suitable to be popularized in the sand-sand loam area and the western Yunnan region in the mid-lower reaches of the Yangtze River, and because of the better resistance to powdery mildew, it can exert its synergistic potential in the recurrence area of ​​powdery mildew. First, the appropriate sowing. Control the appropriate basic seedlings. The middle and lower reaches of the Yangtze River will be planted on October 25-30. The basic seedlings will be controlled at about 180,000 yuan/mu. The seedlings will be planted along the Huaihe and Longxi regions on October 20-25. The basic seedlings will be controlled at about 150,000 yuan/mu. When drought occurs, it is necessary to timely watering and planting seedlings, and strive to get 1-2 main stems over the winter. Second, rational fertilization. During the whole growth period, 12 kg of pure nitrogen was used in Mushi, and 5-6 kg of phosphorus and potassium were used. (1) Nitrogen Fertilizer, Base Fertilizer: Topdressing = 7:3, Balanced Relay Fertilizer in Topdressing accounts for about 10-15%, Jointing Fertilizer occupies about 15%, and is applied in the inverted 3-leaf stage; (2) Phosphorus, Potassium Fertilizer, Base Fertilizer: Topdressing = 5:5, The application of topdressing time is 5-7 leaf stage, and multiple fertilizers can also be used in topdressing. Third, do a good job of field pests and weed control. The cultivars are shorter (about 85 cm) and are prone to weed damage. Weed control must be taken care of before and mid-term; when weeds are 2-3 leaves, 6.5-percent mussels are used in 50-75 ml of mussels + 75% of giant stars 1-1.5 mu. The 50 kg spray of water on the water can effectively prevent and control the malignant grass weeds and broad-leaved weeds such as Aegilops umbellatus and pig bristles. In the late wheat field, we must pay attention to the control of sheath blight, rust, head blight and insect pests. Fourth, pay attention to the post-root dressing. For extra-root fertilizers, a large amount of elemental fertilizers and trace element fertilizers should be used in conjunction with the application. In particular, attention should be paid to the fact that the proportioning concentration should not be too large. Otherwise, the leaves may be easily burned. The spraying period should be appropriate and the frequency should be appropriate. Trace element fertilizers, such as ASUS 828, American Star, and High Yield Spirit, etc., should be selected one at a time during booting and filling, and a large number of elemental fertilizers such as potassium dihydrogen phosphate can be sprayed 1-2 times during the booting period, and then sprayed during the grain filling period. 3-4 times, through the spray can promote the transport of carbohydrates to the grain, increase the carbohydrate content in the grain, reduce the crude protein content of grain, improve quality.
