How to improve the fruit setting rate in Almond Garden
At present, the heat metering market commonly used heat table is divided into mechanical heat meter(mechanical energy meter) and ultrasonic heat meter(ultrasonic energy meter).Heat energy meter is suitable for measuring
the heat exchange, known as the heat transfer fluid or liquid absorbing thermal
energy conversion equipment, which consists of a flow sensor, temperature
sensor and heat calculator three parts. Heat energy meter (thermal meter), also
known as Heat Meters, heat energy calculator, both measure heating system for
heat and also measure heat absorption cooling system.
Heat energy meter (heat meter) is used to
measure and display the water flow through the heat exchange system release or
absorb heat. Heat energy meter, is also known as energy meters. The heat energy
meters are installed at the inlet pipe or outlet pipe to measure accurate
metering and intelligent control of charges of the heat consumption. Its working
principle is to install Heat Energy Meters in the heat exchange system, when
water flows through the system, according to the supply and return water flow
temperature, from the data from the flow sensors and temperature sensor as well
as the water flow time, the heat energy meter will calculate the released and
absorbed energy through the calculator.

2. Reasonable pruning, timely adjustment of tree structure. In winter, when it is cut, it is necessary to control the weaker and weaker, and adjust the tree potential to the level of moderate dominance. Pruning of the resulting branches and combinations, appropriate short cuts to ensure a reasonable amount of flowers, can adjust the distribution of nutrients during fruit setting. Open the light path to allow the tree to be airy and transparent for the differentiation of flower buds. During the growing season, the leggy branches were dealt with promptly. The result branches and result branches of the internal branch were used for branching, pulling, and supporting, etc., and the branches were rationally placed.
3. Prevent and forecast and prevent frost from happening in time. In the flowering period and young fruit period, listen to the weather forecast at any time. When there is a cold current, preparations for smoke preparation can effectively prevent the occurrence of frost. At the same time, before flowering, the use of spray suppression transpiration agent, spraying salt water and trunk whitening method can delay the flowering period, avoiding the danger of late frost.
4. Flowering tree fertilization during flowering can increase fruit setting rate. Spraying 0.2%～0.3% urea and 0.2%～0.3% borax in the flowering tree all have the effect of increasing fruit setting rate.
5. Flowering bee during the flowering period increases pollination opportunities. Generally, every 1000 mu of apricot flat garden can be placed with 1000 bees.
6. Flowering pollen is sprayed during flowering to improve the pollination effect.
