The suitable period for harvesting wheat is very short. The so-called "wheat cooked for a long time" must be harvested in time. The harvest is too early, the grain is not full and full, the water content is high, and the yield is affected. At the same time, the stalk grain is very moist after harvest, and it is prone to heat and mildew during stacking, resulting in loss. The harvest is too late and the ripening is excessive. It is easy to thresh, break the ear, and lose a lot. When it rains and rains, the loss is even greater.

Appropriate wheat harvest should be based on grain maturity. Generally wax ripening period, that is, the stems and leaves have turned yellow, but there is still elasticity, and wheat can be scratched with nails. This is the best harvest period for unplanted wheat. In this way, the highest yield and best quality can be achieved while reducing losses. However, it is best to leave the seed for harvesting wheat during late maturity. When you encounter a sunny day, you must harvest it in time.

The establishment of wheat seed fields, the selection of seeds and the retention of seeds for successive years not only maintain the purity of the varieties, prevent the degradation of the hybrids, but also increase the excellent characteristics of the varieties. The seed field should select fertile land with better conditions. The amount of sowing should not be too large, and fine management should be carried out to cultivate fine seeds with large grains and large grains. When heading, it is important to remove diseased plants such as wheat smut and head blight, and bring them out of the field and burn them out. When mature, select disease-free plants with the characteristics of this variety, which are well-grown, large-grained, and uniform in maturity, and single-sun-seeds after degranulation, as seed for the next season seed field. The number of panicles was selected to meet the seeds needed for seed field sowing. After the panicle selection, the bad strains of the miscellaneous plants were removed and used as seeds for field production in the next year.

After the wheat seeds are harvested and dried, they can be stored with ash. The plant ash can effectively absorb the moisture and carbon dioxide released by wheat during storage, prevent the wheat from rotting and deteriorating, and because the plant ash is an alkaline substance, it can kill and inhibit the eggs of the moth and the newly hatched larvae. Wheat seeds are eaten by pests. In addition, the use of plant ash storage wheat seeds, does not affect the germination of wheat germ, can be used for both species and edible. Therefore, it is safe, economical, and convenient to store seed with plant-wood ash rather than with seeds for storage. The specific method is: in the sunny storage of wheat seed utensils, such as wooden boxes, cylinders, cans, etc. (boiled pickled vegetables container) washed and dried, the bottom of the container placed a layer of 1-2 cm thick ash. Then according to the ratio of 100:1 wheat and plant ash, mix evenly and place in the container, and put a layer of 2-3 cm thick ash on the wheat seed. Grass ash can be burned with straw and wheat straw, but fresh and unmoistened grass ash should be used.

Hearing aid is a small electronic device that you wear in or behind your ear . It makes some sounds louder so that a person with hearing loss can listen , communicate , and participate more fully in daily activities . The hearing aid can help people hear more in both quiet and noisy situations.
