Two pieces of appreciation of firethorn bonsai
It is suspected that the red clouds are as beautiful as fire when you see the red clouds in front of you, you will feel particularly pleasing to the eye, because it gives people a warm, heroic, auspicious and harmonious feeling.

Du Mu, a poet of the Tang Dynasty, wrote that the author was attracted by the red leaves of the mountains and refused to leave for a long time because he loved the maple forest in the evening and the flowers in February. On the other hand, Mao Zedong wrote the beautiful sentence of "watching the mountains all over the world and dyed all the layers of the forest", which expressed the surging feelings in the author's heart.

Hippophae rhamnoides are also known as "torch fruit", "flame tree" and "rescue food". Wild in Yunnan, Guizhou, Sichuan area can be said to be full of mountains, someone dug up potted plants a long time ago to make bonsai for viewing. It can also be seen at the border between northern Guangdong and Hunan and Jiangxi. After three or five years of raising seedlings in a large area, there will be a middle and upper billet with an encircling diameter of 20 or 30 centimeters, which is rich in resources, which is actually a good thing for closing mountains to cultivate forests and protect the environment. The seedling billet can be made into a variety of bonsai at will. Although it is not as interesting as the wild billet, its elegant demeanor is different.

So, how should firethorn bonsai be managed during the period of hanging fruit? In our northern Guangdong region, Hippophae rhamnoides usually blossoms and bears fruit from early April to mid-April. Usually apply phosphate fertilizer once before flowering and pay attention to enough light. After hanging the fruit, the mixed fertilizer and water of phosphorus and nitrogen are applied once a month to make the fruit big and beautiful. In April and May, it will be special.

Grasp the time and methods of chemical control of cotton
Although the sowing of cotton is late, the development of cotton seedlings is also late. By the first ten days of June, the well-growing cotton fields in the north have now had 7 to 8 true leaves, and some have already budded. Around June 10, most cotton fields will enter the budding stage one after another. On June 10, most cotton fields have three fruit branches, but this year there will be two less fruit branches, and there will be no peaches or fewer peaches, which is not necessarily a bad thing. It can save the work of removing early buds and 1 or 2 fruit branches in the lower part, which is conducive to reducing rotten bolls and stiff bolls. According to the results of the cotton plant survey in Guoxin, the cotton owner is from June 10 to July 10.

Pay close attention to treatment of Cotton Cancer
Fusarium wilt and Verticillium wilt are called "cotton cancer" by cotton farmers. At present, due to the high temperature and heavy rain for many days, the cotton field appears to be "a very good situation". However, during the field investigation, the author found that there are still diseased plants of Fusarium wilt and Verticillium wilt in the cotton field, with the dry edge of the lower leaves extending inward and showing a chlorosis and yellowing shape. the whole plant is poor in growth and relatively short. I especially remind cotton farmers not to take it lightly. First, the characteristics of the disease. Fusarium wilt and Verticillium wilt mainly carry bacteria in soil (Fusarium wilt can survive in soil for 7 ~ 10 years, Verticillium wilt.

Cultivation techniques of cotton K7
Shaping the ideal plant type is the guarantee to realize high-yield and high-quality cotton cultivation. According to the co-extension relationship between cotton leaf age and various organs, the whole process regulation of cotton vegetative growth and the formation of buds and bolls is the key to high-yield cultivation. First, improve the soil fertility and increase the intensity of intensive cultivation, increase the application of potash fertilizer, and improve the utilization rate of fertilizer. 60% nitrogen fertilizer, more than 90% phosphate fertilizer, 100% potassium fertilizer and cottonseed cake were used in the ploughing and ploughing layer before sowing, and the rest was used as topdressing. Second, treat alkali and protect seedlings as early as possible in autumn

Comprehensive adjustment techniques for high density cultivation of cotton 81y3
Variety 81y3 has the characteristics of high boll formation rate per plant, strong boll setting, disease resistance, high yield and high quality. At the same time, 81y3 also has the characteristics of weak growth in seedling stage, stronger growth potential in bud stage, strong growth potential in flowering stage, no premature senescence in later stage and long growth period. In order to obtain high yield and high yield in a large area under the condition of high density cultivation, we must coordinate the relationship between vegetative growth and reproductive growth of cotton under the premise of scientific and rational operation of water and fertilizer, and master the comprehensive regulation techniques of 81-3 high-density and high-yield cultivation.

Prevention and control of "double rot disease" of cotton
Rotten bolls and rotten peaches are common diseases of cotton, which seriously affect the yield and quality of cotton. (1) cause 1. Excessive or late application of nitrogen fertilizer resulted in overgrowth of cotton and closure of field canopy, resulting in weakening of disease resistance of cotton plants. 2. Cotton suffered heavy rain or too much autumn rain in the flower and boll period, excessive humidity in the field and poor drainage, resulting in the breeding and invasion of pathogens. 3. Cotton suffers from red rot, anthracnose and boll blight. (2)
