1 Adaptation range Anyone can grow corn, the altitude is in the range of 600-1500m, and the spring wheat planting area can mix Sudan grass. For example, in the area of ​​the inversion zone north of the forest road in Qitai County and south of the forest road. The mountainous area has a high altitude and the climate is cool. The harvested area can be mixed in the area harvested before August 15th, but the growth is slow, the grass yield is low, and the effect is not obvious.
This regulation refers to the mixed use of spring wheat and Sudan grass, and is also suitable for the mixed oasis of barley in the plain oasis. The winter wheat is planted with Sudan grass after the next year.
2 varieties of wheat varieties should choose low, anti-lost, long growing period, high yield varieties, to take anti-backup measures, otherwise the collapsed areas due to poor permeability caused by Sudan grass seedlings death.
3 Mixing and Mixing Seeds 3.1 Mixing and Mixing Mixing The selected spring wheat seeds and Sudan grass seeds are mixed at 5:1, and the barley seeds and Sudan grass seeds are mixed in a ratio of 4:1, and then 200g per 100kg seeds are mixed. In order to prevent smut, use the raft to turn back and forth repeatedly to sown.
3.2 Sowing in Qitai County at the end of March and early April, according to the requirements of wheat, normal hoeing, spring wheat 25kg/667m2, mixed Sudan grass 5kg/667m2; barley 20kg/667m2, mixed Sudan grass 5kg/667m2. Flat sowing, sowing and ditching can be used, but the best effect is the sowing effect, and the sowing depth is 3~5cm.
4 Fertilization and watering do not change the normal boiling water and fertilization of wheat in the growing season before the wheat harvest. Immediately after the wheat harvest, the field wheat straw was pulled and the water was poured in time. Head water is an important means to determine the benefits of mixing. It requires pouring and pouring, preventing cross-irrigation, pouring water for 7 to 10 days, and applying 81Okg/667m2 of urea. The third water is poured for 10 to 15 days to ensure a good harvest. Weather, lyrical watering.
5 Pharmacy to control weeds mixed with Sudan grassland blocks, due to different land plots and weeds, different control measures were adopted. Control broad-leaved weeds, use 2,4-D vinegar 70mg/667m2 to water 20kg, control oat-based monocotyledon weeds, use wild swallow, use 64% wettability in oat grass 2~4 leaves Powder (US) 104g / 667m2 (plus active agent), or 25% wild swallow (domestic) 230 ~ 360ng / 667m2 spray 20kg of water. When using 2,4-D butyl ester to weed, pay attention to whether there are broad-leaved crops around to avoid crop damage.
6 The best harvesting period of the Sudanese grass after timely harvesting is 80% of the Sudan grass flower. At this time, the grass has the highest nutritional value, timely mechanical harvesting and modulation.
