Select autumn harvest timing

Timely harvesting is a measure to increase production without any additional input, but different crops have their own suitable harvesting periods. Harvesting within the appropriate period can yield high yield and quality. Maize corn is harvested at the ripening stage. At this point, the leaves of the ear of the ear become white and dry, the grain filling stops, the “dairy line” disappears, the base hardens, and the water content is about 30%. However, the current phenomenon of premature harvest is generally present in production, especially for some varieties with pseudo-maturity. Generally, when the loquat leaves become white or when the top of the grains becomes hard, they are harvested. The actual harvest time is 7 -10 days, at this time the kernel weight is only about 90% of the harvest. The harvest of sorghum sorghum is suitable at the end of waxing. At this time, the grain from the top of the ear to the middle and lower part has become hard and has an inherent color; the grain at the base of the ear has been solidified in a waxy shape, and although it has not hardened, no juice has flowed out when the skin is cut by hand. . Soybeans are harvested at the end of the yellow maturation period. At this point, the plants and pods all became yellow-brown, most of the leaves fell off, and the grains in the pods were detached from the moltings and the hand was rattled. The roots of sweet potato sweet potatoes are vegetative and have no obvious maturation characteristics. As long as conditions are right, they can continue to grow. In production, generally, the harvest begins when the ground temperature is 18°C; the preserved sweet potatoes start from mid-October and are collected before the frost falls. Peanuts and peanuts should be harvested at an appropriate period and should generally be determined based on the plant's appearance and fruit maturity. From the plant's appearance, the upper leaves turn yellow, the middle and lower leaves turn from green to yellow and gradually fall off, and the stems turn yellow-green; from the development of the mangos, in the normal years, most of the pods have a mature symbol. In some places, the harvesting period is determined solely by the number of days of fertility, and no specific observations and analyses are performed, often resulting in losses from early morning to evening. Mungbeans When two-thirds of the pods on the plants turn dark brown, they should be harvested in time. However, due to inconsistent maturation of pods on the main branches and branches, they can be harvested in batches to reduce losses and improve yield and quality. , Mature batch harvested.
