It is difficult to do well in raising orchids in July. 5 prevention and maintenance becomes simple.

As the saying goes, "it is difficult to raise orchids in July", because of the July weather, high temperature and humidity, a big sun and a torrential rain, orchids are most afraid of this kind of weather. Therefore, if you want to make it easy to raise orchids in July, you should do a good job: sun protection, dry and wet protection, high temperature protection, disease prevention and pest prevention, and typhoon prevention.

There are two seasons in July, Lesser Heat (June-8) and Greater Heat (22nd-24th). The monthly average temperature is more than 30 ℃, which is the highest month of the year. Therefore, the main task in July is to strengthen shading, use a shading net with a shading rate of about 70%, and do not close the curtain until the sun does not reach the blue leaves.

In addition, it is necessary to do a good job in the following "five defenses":

1. Sunscreen

Due to the extremely hot weather, it is necessary to strengthen the ventilation and cooling work of orchid houses, which is the top priority of orchid cultivation in July. In muggy weather, ventilator fans and miniature 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. But try not to sprinkle the orchid plant with water, and the sprayer should be opened carefully so as not to get wet and create conditions for the reproduction of viruses and germs.

2. Prevent dryness and wetness

If it is dry and hot with little rain, the basin soil is easy to dry to the end, pay attention to keep the basin soil moist, water thoroughly, and increase the number of times. Water should be irrigated from the edge of the basin, do not use the immersion method to water, spray as little as possible, so as not to pour water into the heart leaves to cause rot. However, the basin soil should not be too wet for a long time to avoid causing root rot, stem rot, soft rot and rotten buds. Water management is also the focus of orchid cultivation in July.

3. High temperature protection

July high temperature, flower friends if you want to fertilize, try to use orchid special organic liquid fertilizer, diluted 500 times to irrigate the root, once every half a month. If the temperature continues to rise, it is better to spray foliar fertilizer. 1000 times orchid organic liquid fertilizer and 0.1% potassium dihydrogen phosphate can be used alternately to supplement nutrients, promote exuberant growth, grow seedlings and strong seedlings, and lay the foundation for sprouting and flowering in the coming year.

Generally speaking, the orchid is sprayed with foliar fertilizer in the evening and the leaves are washed the next morning to prevent the accumulation of fertilizer from causing damage to the seedlings caused by the high temperature sun, and it can also accelerate the absorption rate of the orchid foliage.

4. Prevention of diseases and insect pests

Raise orchids in July, the most prone to a variety of diseases and insect pests, so insecticidal and sterilization work can not be relaxed. It is best to use hydrazine acaridine to control the fixed insects of shell insects and eliminate red spiders. July is also a high incidence period of soft rot, stem rot, brown spot and anthrax, so it is necessary to do a good job in disease prevention. Sterilization and disease prevention should be sprayed once a week to prevent bacterial and viral infection. In addition, should choose cool evening application, the liquid is not too strong, in order to prevent drug damage.

5. Guard against typhoon

A typhoon has already appeared in July, so it is necessary to make good preparations to prevent it from overturning the bowl and breaking the orchid leaves. It is necessary to take rain shelter measures to prevent torrential rains and cause losses. In addition, the high temperature in July, 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.
