White dew is the season of harvest and the season of sowing. The rich northeast plain began to harvest millet, soybeans and sorghum. The autumn harvest crops in North China are mature, and the cotton in the north and south of the Yangtze River is being vomited and entering the season of comprehensive batch harvesting. Different crops have different harvests during the Bailu period. Huinong.com is here to introduce you to the harvest of different crops in autumn. Corn: The harvest of corn is in the ripening period. At this time, the leaves of the ear are white and dry, the grain filling stops, the "milk line" disappears, the base becomes hard, and the water content is about 30%. However, there is a widespread premature harvest in production. This is especially true for some corn varieties with pseudo-maturing. Generally, when the leaves become white or the top of the seeds hardens, the harvest begins. The actual yield is 7~. At 10 days, the grain weight at this time was only about 90% of the suitable harvest. Sorghum: The harvest of sorghum is at the end of waxing. At this time, the grains from the top to the middle of the ear have become hard and have an inherent color. The seeds at the base of the ear have solidified into a waxy shape. Although they have not yet hardened, there is no juice flowing out when the skin is cut by hand. Millet: The harvest of millet is in the ripening period. At this time, the plant has green leaves and yellow stalks, and all the granules have an inherent color. The seeds are powdery or horny and relatively hard, and are not easily broken by nails. Rice: The harvest of rice is suitable in the late stage of yellow ripening. In order to sow wheat in time, the wheat can be harvested in advance to the middle of yellow ripening. Soy: The harvest of soybeans is suitable at the end of the yellow ripening period. At this time, the plants and pods all turned yellow-brown, and most of the leaves fell off. The seeds inside the pods were separated from the pods, and the hand was shaken. Mung beans: When 2/3 of the pods on the plants turn dark brown, they should be harvested in time. However, due to the inconsistent maturity of the pods on the main branches and branches, in order to reduce the loss and increase the yield and quality, the pods can be picked in batches and mature batches are harvested. Adzuki Bean: The red bean has a long flowering period, and the pods are very inconsistent in maturity. It is often that the bottom pod is ripe, and the upper part is still grouting. It is best to use the method of harvesting by stages, and harvest a batch of mature batches. If the planting area is large, it can also be harvested when 2/3 of the whole pod becomes white-yellow. Sweet potato: The root of sweet potato is an asexual vegetative body with no obvious maturity characteristics. As long as the conditions are suitable, it can continue to grow. In production, the harvest is generally started at a ground temperature of 18 ° C. The sweet potato that has been planted is harvested from mid-October until the frost falls. Peanut: The harvest of peanuts should be determined according to the plant's longitude and pod maturity. From the aspect of plant appearance, when the upper leaves turn yellow, the middle and lower leaves turn from green to yellow and gradually fall off, and the stems can be harvested when they turn yellow-green. From the perspective of pod development, when the shell is hardened, the outer peel is turned from yellowish brown to blue-brown, and the netted pattern is clear. The white sponge of the endocarp shrinks and ruptures, and presents a dark brown with metallic luster. The kernel is full and thin, and presents The color inherent in this variety can be harvested. In some places, the harvest period is determined by the number of days of birth. Without specific observation and analysis, it is often early or late, which is easy to cause losses. Sesame: Characteristics of plants harvested at the right time: Most of the leaves are yellow, of which more than 2/3 have fallen off; the capsule is yellow-brown, the lower part has been partially cracked, the upper part of the capsule is yellowish or yellow-green, and it is still tightly closed, and the lower part of the fruit is shaken by hand. The seeds exhibit an inherent color.
