How to strengthen cultivation and management during the cotton bud stage? Keep these technical key points in mind
After cotton transplanting this year, continuous drought and little rain, unstable temperatures, and a long seedling-hardening period seriously affected plant development. In addition, large populations of aphids and red spider mites caused severe damage, leading to a second seedling-hardening in cotton seedlings, with a few seedlings showing red stems all the way to the top and true leaves drying up and falling off. Recent rainfall has alleviated the drought, and seedling conditions have begun to improve. Transplanted cotton now has 7-9 true leaves and has begun to form buds, and cotton after wheat (rapeseed) has also begun to develop, but overall seedling conditions are not as good as in previous years. The bud stage is the most important period in the life of cotton, and the following cultivation and management measures should be emphasized

Free of pests and diseases, off-odors, and soil impurities. II. Raw material handling and cold storage 1. Precooling and moisture removal of raw materials To maintain good freshness and color of the raw materials, fresh mushrooms must be promptly placed in a cold store for precooling and temperature reduction after harvest. According to equipment performance and the moisture content of the fresh mushrooms, maintain an appropriate

What are the taboos of growing bonsai in summer? Keep these five points firmly in mind
1. Avoid fertilizing. In the high temperatures of midsummer, the leaves lose water quickly. Fertilizing at this time will make the solute concentration of the trunk's cells lower than that of the surrounding environment, causing water in the plant cells to flow back into the soil, and the trunk will die of dehydration due to fertilizer damage. 2. Avoid drought. Watering when you remember and not watering when you forget, sometimes leaving it alone for several days in a row, and only quickly replenishing water once the leaves are found to be wilting, after which the leaves return to normal - this is a response of the trunk to adapt to the environment, but if this goes on for a long time, the excessively strong transpiration will eventually make the trunk difficult to recover from serious damage and die of dehydration. 3. Avoid water

I believe none of you will be surprised by this: copper and zinc in the water will kill koi. Of course, this is not news to me either. What I mean is, before you heard the story about a copper-connected heater releasing a large amount of copper into the water and thus killing all the koi, had you ever thought that copper and zinc could kill your koi? Perhaps many of us have not yet heard such a story. Before telling you these things, let me first review some of my own history. Of course, I have been keeping koi for quite a long time.
