The pruning technique of walnut fruit in early fruit period

Pruning should go to Wang Zhuangzhuang, first put back contraction, or put together, reduce the combination of culture sticks group, sparse a variety of useless dense crowded branches, thin branches, leggy branches, so that all types of branches are evenly distributed, especially the inner litchi sticks To be dense and moderate, grow strong and healthy.

The auxiliary branches that have affected the growth of the main lateral branch can be gradually retracted and weakened to give way to the main lateral branch. The degree of pruning should be determined according to the strength of the tree vigor and the cultivation conditions. The tree vigour is strong, the shoots have a large amount of growth, and pruning should be light; otherwise it should be heavy. In the pruning technique, the major branches on the secondary rearing branches are first sparsely removed so that they extend uniaxially. In this way, the influence of auxiliary branches on the main lateral branches can be reduced. One is to improve lighting and the other is to save nutrients. However, the resulting sticks must be trimmed into compact multi-axis sticks.

Auxiliary branches are the main objects of pruning during this period. They should be treated differently depending on the tree. The trees have space for long-term retention and allow them to have as many results as possible. Small spaces can be retracted in time. All auxiliary branches must be controlled so that they can be promptly retreated or even eliminated.

The leggy branches within the canopy should generally be removed, and those with voids should be retained as appropriate and cultivated into fruiting branches of the internal organs.

Small 2D LiDAR Sensor

IT02S, is JRT new product in the early 2019, which is a single-point LiDAR sensor, also called tof distance sensor. With a micro size of 46x17x7mm, customers can widely use in many Laser Measurement Solutions. The lidar distance sensor can measure 12m short-range with high frequency up to 100hz. It's great for Unmanned Aerial Systems. If you need us send you data sheet and spec for this products, offering sample as well, pls tell us, thank you.
