The cotton growers control the cotton plant long and have been using the regulators to reduce the safety of the process. The mu dose is: Bud stage 0.5-1g, early flowering stage 1.5-2g, flowering period 3-4g, and the application rate before the topping is 4 - 5 grams, heavy control, said "four doors off the lock", all using the former light after heavy control mode. The growth characteristics of the currently planted cotton varieties are no longer suitable for the former lighter, later heavy and chemically controlled models, because this model is most suitable for late-maturing varieties with slow early growth and rapid growth in the later period, but due to climate change in recent years, summer and autumn There is plenty of rain, more rainy days, and cotton bolls are delayed. Farmers like to plant early-maturing varieties that grow rapidly in the early stage and have stable growth in the later period. They are more suitable for the chemical control mode that is promoted before and after the control. After the pre-control, the middle and early stages of the anaesthesia are mainly controlled, and the amount and frequency of the controlled dose should be combined. Look at: Look at the sky (clear or rain), look at the land (strong or weak land), see the seedlings (strong or weak), use a few times in anticipation and adopt the principle of less control. The cotton is mainly promoted in the later period. For the cotton field with moderate growth, the 800-1000-fold potassium dihydrogen phosphate solution is sprayed on the leaves to promote reproductive growth and promote flower and bell protection. The cotton field can show signs of premature aging and weak growth. Taking foliar spray of 300-500 times urea solution to promote reproductive growth, play a role in improving the function of the leaves, the cotton field with signs of prosperous growth, should be timely spraying shrinkage regulation. A greenhouse(also called hothouse)is a building or complex in which allow for greater control over the growing environment of plants. Depending upon the technical specification of a greenhouse, key factors which may be controlled include temperature, levels of light and shade, irrigation, fertilizer application, and atmospheric humidity. Greenhouse may be used to overcome shortcomings in the growing qualities of a piece of land, such as a short growing season or poor light levels, greenhouses are often used for growing flowers, vegetables, fruits, transplants and seedlings. Greenhouses can be divided into glass greenhouses and plastic greenhouses. Plastics mostly used are polyethylene film and multiwall sheets of polycarbonate material, or PMMA acrylic glass. Commercial glass greenhouse are often high-tech production facilities for vegetables or flowers. The glass greenhouse are filled with equipment such as screening installations, heating, cooling and lighting, and may be automatically controlled by a computer.
