Five measures to combat drought in high temperature weather fruit trees

      In the high temperature season , the continuous high temperature weather has a great influence on the growth and development of fruit trees. To cope with the management of high-temperature weather orchards, we must pay close attention to the implementation of drought-fighting measures.  

 

    1. Irrigation and drought resistance. It is necessary to replenish moisture in time to keep the soil in the roots of the fruit trees moist. If there are irrigation conditions, it is necessary to timely flood and drought; if there is no irrigation condition, watering should be done once every half month, and the amount of water per acre should be no less than 3,000 kg. Especially in young orchards, because the root system is shallow, it is necessary to give water several times in time to supplement the water of the tree and promote normal growth and development.   

 

    2 , covering grass and protecting you. Covering grass can keep water and cool, loosen soil and improve soil microbes. Before weeding, we should first remove the weeds in the garden and then cover the grass. Cover straws, soft grasses, etc. between the rows of fruit trees or under the tree trays to ensure that the soil around the trees is not exposed. Generally, the thickness of grass is more than 10 cm, and more than 1000 kg of grass is planted per acre .   

 

    3 , thin fertilizer and diligent application. Timely, small, and multiple supplements. Topdressing once a month, 30 kg of high-concentration compound fertilizer or 15 kg of urea per mu .   

 

    4 , prevention and treatment of insects. At present, attention should be paid to the control of aphids such as spider mites, aphids and moths (top leaf moth, gold moth) and pear star caterpillars. Prevention and control of pests and diseases should be targeted, pay attention to alternate, rotate the use of different mechanisms of insecticides, fungicides, to avoid the emergence of resistance to pests and diseases.   

 

    5 , root dressing. After drought damage tree roots, weak ability to absorb fertilizer, root fertilizer not immediately, choice of 0.1 - 0.2% potassium dihydrogen phosphate, 0.3% urea, and an efficient, fast-acting fertilizer like extraradical top dressing. Every 5 - 7 days or spray, and even spray 2--3 times. It is also possible to apply decomposed high-quality organic fertilizer or urea to promote new root growth.

Diamond Wire For Silicon Cutting

The advantages of Diamond Wire cutting technology are huge, and it can replace the traditional mortar wire. Diamond wire is mainly used in the cutting of hard and brittle materials such as crystalline silicon and sapphire. Compared with traditional mortar steel wire cutting, it has high efficiency (4-5 times the cutting speed), less loss and high chip yield (15-20% more silicon). The advantages of low environmental pollution (no organic liquid) and high product quality. Among the diamond wire, electroplated diamond wire is widely favored by the market for its outstanding advantages of low wire consumption per piece, small wire diameter and high cutting efficiency, and is superior to resin diamond wire.
