Combine harvesting requires 3 to 10 days of direct harvesting to require the use of keratinous herbicides such as Diquat, Glufosinate, and Diuron, to reduce the water content of the pods to 10%. Harvested at 20%. The advantage of direct harvesting is that it can wait until almost all of the pods are ripe and then harvested, but the loss of seed granules that are harvested too late is correspondingly increased, and the seed loss is 5-20 kg/hm2 when the management level is higher. The effect of drying with 0.95 kg/hm2 of diquat and glufosinate was the same. When 60% to 75% of the pods in the field turned brown, the highest yield was obtained after spraying the herbicide.
The efficiency of threshing with a thresher or a combination is related to the moisture content of the seed and depends on the speed of the threshing cylinder and the gap of the intaglio. If the speed of the threshing roller is too fast or the gap between the intaglio plates is too small, the mechanical and physiological damage of the seed is easily caused. , which reduces the germination rate of the seeds, which is more serious after the pods have fully matured. Therefore, the machine must be commissioned before the threshing or field harvester harvests to ensure that the seeds are not damaged. In addition, maturation period rainfall has a great influence on alfalfa seed yield. Only 5 mm of precipitation can cause a great loss of yield. The loss of 10 to 20 mm of precipitation seed yield can reach more than 75%, while the rainfall of the seed The germination rate and quality have a negative impact on production, so the harvest must be chosen during periods of no rainfall.
Including horn pepper cultivation area is large, and shandong, shanxi, Inner Mongolia, jilin, heilongjiang area quite, in the above major planting base, the most excellent varieties of green semillon.Green fruit semillon pepper seeds bulky straight, high yield, disease resistance, strong adaptability, and very mature for his age.Ox horn pepper varieties are the best on the market.On the base of all have large area.
Alfalfa seeds harvested and processed
Generally, the harvest time is determined according to the color of the pod and the moisture content of the seed. There are two kinds of harvest methods for the large-area seed field, that is, the straw after drying is dried and then threshed or directly harvested by a combine harvester. The former is suitable for seed fields with more weeds, late maturation of seeds, or more dewy leaves. When visual observations indicate that 2/3-3/4 of the pods turn brown in the field, the water content is reduced to 12% after drying. The threshing was carried out at ~18%, and the loss of seeds during the harvest process was not more than 5 to 10 kg/hm2 under the optimum management level. However, when windy weather is encountered during the harvest period, the loss rate of seeds can reach more than 50%. Therefore, it is better to harvest directly from the combine harvester in regions where windy weather occurs frequently.
