Fall selection considerations

Into the fall, various crops have matured and are about to be harvested. In order to ensure that there will be good seeds coming into the land next year, field selection must be done at the time of autumn harvest. So, how to choose farmland? Should pay attention to the following aspects:

The principle of field selection must first be based on the local climatic conditions and soil conditions. For areas with long frost-free periods, fertile soil, and high cultivation levels, the late-maturing varieties with good fertilizer and lodging resistance should be selected; soil fertility should be poor. In drought-prone and low-cultivated areas, we must choose to bear stubborn and early-maturing varieties; in areas with short frost-free periods and high dry terrain, cold-tolerant and earlier-maturing species should be selected; areas with low salinity and high salinity should be selected. You need to choose anti-mite and salt-tolerant varieties. Secondly, according to the characteristics of high yield, disease resistance, and strong adaptability, the local main cultivars and collocations should be identified, and degraded and impure cultivars with low yield and poor stress resistance should be eliminated.

The criteria for field selection depend on the local planting experience for many years and the fertility status of autumn crops. The following conditions must be taken into consideration when selecting the plant: the plants grow robustly, do not fall flat, have no disease, no insect damage, no mechanical wear, and reflect the organism of this species. Characteristics and botany characteristics, high purity, good color, large spikes, full kernels, good quality, etc. Only such seeds will get high yields in the next year.

Field selection methods In addition to plant selection, corn should also be selected. Because corn is a dominant crop in the middle, that is, the grain in the middle and middle and lower parts of corn cobs is full and has strong vitality, and it has the best genetic advantage, and has stronger yield-increasing potential than the top and the root. Therefore, this part of grains should be selected as seeds. With the exception of corn, all grass crops such as sorghum, millet, sorghum, and rice have top dominance. That is, the top and upper middle grains of the ear are full, well-developed, and have strong vitality, which can best reflect the characteristics of the variety. Due to the strong genetic advantage of strong fertility, it should be selected to retain seeds in this part of the seed.

The size of the seed moisture is an important factor in determining whether the seeds can safely pass through the winter. Plants and seeds picked from the fields should not be piled in the yard, but they should be fastened separately to allow them to be dehydrated quickly and give priority to threshing. You have to play singles and put labels on them to prevent them from mixing. Before entering the stock, the seeds must be strictly checked for moisture. Seeds that do not meet the moisture content standard are absolutely prohibited from entering the warehouse to prevent moldy or frozen seed umbilization and reduce the germination rate.
