Recently, some cotton areas in our province have fallen to heavy rain. For cotton after long drought, it is easy to cause red stem blight, and precautions should be taken. Symptoms of symptoms Red leaf blight is a physiological disease that starts from the point of growth of the main stem or the top of the fruit branch and generally develops from top to bottom and from outside to inside. The roots are thick and short, and the fibrous roots are less stunted. The diseased leaves first appeared yellow, followed by red spots, and finally the entire leaves turned red and the veins remained green. Stems and petiole bases often develop brown to dark brown strips or irregular lesions, and are susceptible to infection by certain pathogens such as Rhizoctonia solani and leaf spot pathogens, accelerating the death of cotton plants. The main stem blighted but the anatomic catheter was colorless. Control methods Cotton stem blight caused by a variety of reasons, when the climate changes suddenly, some of the poor cultivation environment, physiological dysfunctional cotton susceptible to stem blight disease. Prevention and treatment of cotton stem blight, mainly to grasp the following points: 1. Control on the promotion, to enhance the cotton strain resistance. First, for the growing cotton, the use of plant growth retardants shrinking security or promote strong control of prosperous, with 2 to 3 grams per acre shrinkage or 2 to 12 ml of colostrum 8 to 12 ml of water spray, can be effective Promote the stability of the soil; Second, the cotton field of soil compaction, timely cultivating ventilation, enhance permeability performance; Third, the cotton fields on the lower ground, pay attention to grooming silo, promote cotton root down, the fourth is the implementation of plastic film Cover the cultivated cotton field, immediately remove the film, so that the cotton root to the depth development. 2. Increase potash fertilizer and improve fertilizer efficiency. The lack of potassium is one of the leading factors inducing stem blight of cotton leaves. For the two types of cotton fields with potential shortage of potassium or less potassium, 10-15 kg of potassium fertilizer should be added per acre. One can meet the needs of cotton for potassium fertilizer; second, the structure of fertilizer ratio in cotton fields can be adjusted to increase the utilization rate of nitrogen fertilizer and phosphate fertilizer. 3. Spray fertilizers from outside the roots to improve the oxygen supply of the root system. In the case of cotton with red leaf blight, as long as cotton leaves are not withered yet, the main stem growth point is still viable, and fertigation can be used to restore fertility quickly. The first is to use 100 ml of humic acid active liquid fertilizer per acre and 45 kg of water to spray, both for rapid fertilization and improved soil oxygen supply; second is to use 0.2% potassium dihydrogen phosphate solution and prevent spotting. Sick germicides such as Maoling Mix Spray. Can add a lot of elements and trace elements, both bactericidal effect.
Millets are a group of highly variable small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Millets are important crops in the semiarid tropics of Asia and Africa (especially in India, Mali, Nigeria, and Niger), with 97% of millet production in developing countries. The crop is favored due to its productivity and short growing season under dry, high-temperature conditions. In a 100 gram serving, raw millet provides 378 calories and is a rich source (20% or more of the Daily Value, DV) of protein, dietary fiber, several B vitamins and numerous dietary minerals, especially manganese at 76% DV (USDA nutrient table). Raw millet is 9% water, 73% carbohydrates, 4% fat and 11% protein.
