Summer Harvest Summer Breed Notes


One is timely harvesting timely harvest is an important measure of high wheat yield. The harvest of wheat must be mastered at the end of waxing. The grain weight is highest at this stage, and the yield is also the highest. The sign of the late waxing stage is that the leaves of the plants are yellowing, and the internodes are golden yellow, and the first internodes are slightly green. The grains are waxy and can be cut off by the nails. For the loosing wheat fields, the lighter lodging level can be harvested with a combine harvester; if the lodging is serious, artificial harvesting is required to make the granules go back to the warehouse. After the wheat is harvested, it should be promptly dried to prevent deterioration of the mold.

Second, the core content of high-yielding cultivation of summer corn sown by robbers is “one increase and four changes”, that is, a reasonable increase in planting density, replanting of tight-tolerance varieties, replanting of crops for direct seeding, extensive fertilization for fertilization, and artificial planting Mechanized operation. Summer harvest is carried out at the same time. After wheat is harvested, it should be immediately planted with corn, highlighting the word “early”. Seeding should use fine-seeding machinery, broadcast straight, broadcast fine, broadcast uniform, broadcast 3-5 cm deep, and prevent uneven sowing. In the plot with insufficient lyrics, it is necessary to pour well the headwaters in time to ensure that all seedlings are broadcast. In terms of species selection, varieties suitable for local planting should be selected, and seed coating or chemical seed dressing should be adopted, and the seeds should be sunned for 1-2 days before sowing so as to increase seed emergence rate and disease resistance.

The third is to do a good job before and after the emergence of seedling management corn before and after emergence, we must promptly prevent and control field weeds and corn rough dwarf disease, earthworms, armyworm and other pests and diseases. During the period of three-leaf seedlings and five-leaf seedlings, the seedling density of corn should be compatible with the requirements of the varieties. Generally, compacted maize seedlings are kept in 4000-4700 seedlings per mu, and large ear-type seedlings are kept in 3200-3700 seedlings per mu. Planting density increases with the increase of yield indicators. At the same time to do nitrogen, phosphorus, potassium and other balanced fertilization, determine the amount of fertilizer based on yield indicators and the basis of fertility, pay attention to increase phosphorus and potassium fertilizer and trace fertilizer. Lightly Miao Fei, heavy ear fertilizer, make up the recovery of grain fertilizer. Promotes ditching or acupuncture and prohibits spreading.
