Wheat from jointing to heading is the most prosperous period of growth in life. It needs large amount of fertilizer and needs more fertilizer. It is very important to seize the high yield of wheat. Jointing, panicle fat should see Miao Qiao Shi. For groups with poor wheat growth and weak seedlings, the joint fertilizer should be applied early, and the percentage of tillers and spikes should be increased so as to strive for many spikes and spikes. The topdressing amount may account for 10%-15% of the total amount of fertilizer applied, and urea can be applied to 3-4 kg of furrow or acupoint per acre. For vigorously growing wheat seedlings, due to appropriate groups, the number of panicles is generally guaranteed, and the major spikes should be attacked. The joints should be properly controlled for fertilizer and water to prevent lodging, until the leaf color fades, the first internode is fixed, and the second inter-season is fixed. When it is rapidly elongating, water and fertilizer are added to increase the grain size. For large groups, large leaf area, dark green leaves, drooping leaves with large seedlings, there is a risk of lodging, mainly should control the fertilizer and water, deep middle farmland, inhibit post-natal childbirth, if conditions can be sprayed CCC, short Plants, strong stalks down. When the sword blade is exposed, if the leaf color fades, then make up the panicle fertilizer.
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination; and the use of electromagnetic radiation such as ultraviolet light.
