Foot water is pregnant. The booting stage is the period of most water demand. Generally, the water requirement for plant growth at the booting stage of corn is about 27%-38% of the total water requirement during the whole growth period. The soil moisture in this period should be maintained at 70%-75% of the field water holding capacity. Fertilize with water to meet the fertilizer and water needs of corn growth and development.
Heavy application of panicle fertilizer. The application of panicle fertilizer can not only improve the photosynthesis efficiency, but also promote the growth of the panicle leaves and the upper and lower leaves, and can extend the life of the leaves and promote the fullness of the seeds. The application time of panicle fertilizer is related to corn variety and soil fertility. In general, early-maturing varieties are used in 15-16 slices of visible leaves or 8-10 slices of unfolded leaves; medium-late-maturing varieties are suitable for application in 15-17 slices of visible leaves or 11-12 slices of leaves, with sufficient base fertilizer and vigorous growth. For plots, it is advisable to apply panicle fertilizer slowly. It is advisable to start planting a small number of plants in the whole field; the growth potential of lean soil with insufficient base fertilizer is poor, and the ear fertilizer should be applied early. Spike fertilizer should use quick-acting nitrogen fertilizer. Generally, 25-35 kg of ammonium bicarbonate is applied per acre. If urea is used, 7.5-10 kg per acre can be applied.
YT-80 turning machines focus on large enterprises and export customers. Its technology is from Japan. It is automatic line, incorporated with most updated electrical, hydraulic and pneumatic technologies, particularly for high-accuracy, high-productivity and high-reliability turning bearings.Machines can be divided into Outer ring bearing ring machine and Inner ring bearing ring machine.
Automatic Bearing Ring Lathe Machine is a special equipment for turning inner and outer rings of small and medium-sized rolling bearings. The main processing objects are 628-6213 and other models. The assembly line is composed of several single function main machines and various auxiliary machines, which are connected through the slideway to complete the processing of the inner and outer rings of the bearing. It is suitable for the mass production of the inner and outer rings of the rolling bearings. The main engine undertakes the following tasks: inner hole, groove of end face, chamfering of inner and outer rings, separation of inner and outer rings, middle groove and side groove of inner and outer rings. The auxiliary equipment consists of disc feeder, elevator (floor type and bed type), scrap iron crusher, etc. The assembly line integrates mechanical and electrical, pneumatic, hydraulic in one, automatic feeding, processing and cutting, with high degree of automation and short processing cycle. It can flexibly form automatic or semi-automatic assembly lines with different forms and different lengths according to different raw materials and different process requirements of users. The machining accuracy is 0.01mm and the processing technology reaches the domestic advanced level.The machine can choose for double slide turning machine and single slide turning machine.
More than 100 pcs of YUTAI Turning Machines are running in India which supplies best quality products to world class bearing manufacturer SKF, FAG, NSK, NBC etc.
