More than 2/3 of the weather is a sunny day with scorching sun in the sky. Therefore, the main task this month is to strengthen shading, use about 70% of the shading net, and do not close the curtain until the sun does not reach the orchid leaves. Second, due to the extremely hot weather, it is necessary to strengthen ventilation and cooling work. In muggy weather, ventilator fans and mini electric fans can be used to blow with a breeze to promote air circulation. At the same time, water is often sprinkled on the ground to cool down to prevent hot heat from hurting orchids. However, try not to sprinkle the orchid plant with water, and the sprayer should be opened carefully, so as not to create conditions for the reproduction of viruses and germs. Third, if dry, hot and little rain, the basin soil is easy to dry to the end, pay attention to the wet basin soil, watering thoroughly, the frequency should be increased, do not use the soaking method to water, as far as possible less water spray, so as not to pour water into the heart of the leaves to cause rot.

Fourth, high temperature this month, it is forbidden to apply organic or inorganic fertilizer to roots, and it is better to apply foliar fertilizer for fertilization. 1/1000 urea plus 1/1000 potassium dihydrogen phosphate or biological bacterial fertilizer can be used alternately to supplement nutrients, promote exuberant growth, grow seedlings and strengthen seedlings, and lay the foundation for germination and flowering in the coming year. Generally speaking, spray in the evening and wash the leaves the next morning to prevent the accumulation of fertilizer in the leaves caused by the high temperature sun. Fifth, all kinds of diseases and insect pests are most likely to occur this month, so the work of disinfestation and sterilization should not be relaxed. The best pesticide to control shell insects is chlorinated fruit, and trichloropropanol is the best way to kill red spiders. Sterilization and disease prevention should be alternately sprayed with agricultural streptomycin, methyl topiramate, chlorothalonil and Bordeaux wave once a week to prevent bacterial and viral infection. Should choose cool evening application, the liquid should not be too strong to prevent drug damage. Sixth, for the bluegrass that has just been put into the pot, it should be well managed: first, not to fertilize the root system; second, not to bask in the sun; third, not to put it in a high-temperature and airtight place, so as to avoid losses. 7. There has already been a typhoon this month, so it is necessary to do a good job in Taiwan prevention to prevent the typhoon from overturning the bowl and breaking the orchid leaves. It is necessary to take rain shelter measures to prevent heavy rain from hitting and causing losses. Eighth, "it is difficult to raise orchids in July." Sun protection, high temperature protection, rainstorm prevention, typhoon prevention, disease prevention and pest control are all key issues for the success or failure of orchid cultivation. Ninth, taboo: high temperature this month, do not turn the basin, change the soil, split, even if the need for introduction, it is best to wait until before and after the Autumn Equinox.
