Apple bagging considerations
Short range distance sensors from JRT combine highly precise measurement results with quick and reliable response. Short distance sensor module use single-transmit and single-receive measurement technology and can be used to measure a distance or monitor the slow moving objects. For the laser pointer distance measure, also called optical range sensor, can measure legth, width, depth. Laser rangefinder transducer with rxtx has been widely used to industries.

Red varieties, such as New Red Star, Jonagold, Red Fuji, etc., are generally covered in bags within 25-40 days after flowering, ie within half a month of fruits and vegetables. It is generally conducted in early June and the wheat is completely set before it is closed. The growth period of the red Fuji fruit in the bag should generally be more than 50 days.
Second, bagging method
Before bagging the apple bag, first inflate the bag to make the bag inflated to prevent the paper bag from burning on the fruit surface. Then put the young fruit into the bag and put the fruit in the central part of the bag to fasten the bag. , To expose the fruit counters and blades to the outside of the paper bag. When using a double-layer bag, do not bundle the wire on the handle to prevent wind and rain from swaying the handle and causing fruit drop. Due to the different manufacturers of paper bags, the specifications are different, and the requirements for banding are also tonsils. They should be used as required.
Third, timely calcium
Bagging apples are prone to black spot disease and pox spot disease from before bagging to bag removal, affecting fruit quality and storage performance. The apple should be sprayed 2-3 times with high quality calcium fertilizer before bagging. If the number of calcium sprays prior to bagging is 1-2 times high quality calcium fertilizer, the south spray will be applied once after bagging.
Fourth, regular inspection after bagging
The phenomenon that the bayonet of the bag was loosened, dropped, and bag leaked was found to be corrected at any time. Wind, rain, and after the spraying should be checked, to prevent paper bags close to the fruit surface, affect ventilation, drainage, in order to avoid sunburn.
V. Appropriate amount of thinning to prevent sunburn
In the summer and autumn of high temperature and drought, the branches on the back of the apple tree and the dense inner culprit should be properly removed, but not too much; after the bag is taken, appropriate amount of thinning is performed.
Six, Apple trees after bagging should not be circumcision
Bagging apple girdling can cause black spot disease and water heart disease. It also causes small size, reduced hardness, poor coloring, and prone to sunburn. Therefore, bagging apple trees to promote flower measures to cut, pull branches, twisting branches, picking the heart as well.
Seventh, strengthen pest control
Bagging apples must protect the leaves during growth. The disease is mainly early defoliation, and the pests are mainly leaf-feeding insects such as gold moths and red spiders. Sterilization and insecticide selection DuPont Yi Bao, An Taisheng, green kung fu, extinction and other benefits.
