(1) Apply enough water to make enough water to apply base fertilizer before October 15th, then remove the cotton tree and transport it to the field to let the late autumn peach crack naturally on the cotton tree. Due to the high consumption of cotton stubble, the amount of base fertilizer should be increased. However, the cotton buckwheat sowing late, rely on the main stem into the shift, before the jointing process through the management of fertilizer to control the sub-rong, adjust the group. Therefore, the proportion of urea fertilizer applied to cotton buckwheat can not be too large. In general, 4,000 kg of high quality soil miscellaneous fertilizer, 25 kg of diammonium phosphate, and 15 kg of potassium chloride are used. Nitrogen fertilizers should be concentrated in the jointing stage of wheat.
(II) Selecting superior seeds to increase the growth period of short-lived cotton buckwheat, with fewer tillers, should use high-yield, early-middle panicle and medium-grain wheat varieties such as Henong 321 and 71-3. Before sowing, seeds, sun seeds and pesticides should be selected. The sowing volume should be determined according to the sowing date. On October 15th to the sowing of the frost, the basic seedlings of the mu should reach 350,000 to 400,000; after sowing, the seeds should be sown. Miao should reach 400,000 to 430,000. To ensure the quality of sowing, it is necessary to finely prepare the soil, plant it with a sowing machine, sow depth 3 to 4 centimeters, and make uniform seeding and uniform sowing depth.
(C) winter Li Li (l) enough for overwintering: cotton buckwheat seedlings are weak and weak, poor resistance, winter susceptible to frost damage, must be enough to winter. Put enough water before sowing. It is advisable not to use frozen water to prevent the early spring temperature from rising slowly and affecting the early occurrence of wheat. However, in the event of autumn drought, loss of too fast or robbed planted without picking the bottom of the water, it should be skillfully poured frozen water, should be poured early, after the pouring plan in time to prevent cracking of the soil.
(2) Winter wheat: Winter wheat not only can crack soil cracks, but also can crush crushed litter to reduce water evaporation. After the wheat stopped growing, it was selected in the afternoon on a sunny day and pressed with wheat. Generally lame and sandy soil is lightly pressed; The proper weight of soil viscous weight.
(D) spring management (l) early spring tube: the beginning of the spring surface thawing, the use of bamboo ridge along the ridge to scratch dead leaves, debris, and then began cultivator plan, warming and promote seedlings to promote early-onset.
(2) Fertilizer attack at the jointing stage: The first fertilizer in spring should be postponed to the jointing stage, and the fertilizer should be flooded. The urea fertilizer should be applied in 20 kg. This fertilizer is the maximum benefit period for the fertilizer and water of wheat, which can increase the rate of rent, increase the number of grains per spike and increase grain weight. In addition, it is necessary to pour good booting and flowering grouting water.
(E) pests and weed control before and after the jointing of wheat, with methamphetamine or tribenuron-resistant grass control, wheat stubble can be used to control the fast killing spirit. Wheat sheath blight. Leaf blight, powdery mildew, available streptomyces, triadimefon prevention. During the grain-filling period of wheat, spraying fertilizers such as spray-spraying, Huimanfeng, etc. can also be used to prevent dry hot wind of wheat.
