Black Dragon Wheat Spring Coin Suggestions
Recently, we conducted investigations and investigations on the wheat fields in the area of ​​Heilonggang. Based on the investigation and analysis, we have made a comprehensive analysis and proposed the following recommendations for the spring tube. The period of returning green to the beginning of wheat is the key period of spring management, and it is an important period for promoting the growth of weak seedlings and strengthening strong growth of seedlings, and it is also a key stage for regulating the rational development of wheat groups. The management of spring should strengthen the monitoring of wheat returning to jointing stage and seedlings during the jointing period, with the main purpose of increasing the temperature and keeping the grasshoppers. It should be classified and guided, and the water and fertilizer should be properly transported, and the grain should be preserved for protection, which laid a good foundation for the harvest of wheat. First, all types of wheat should be promptly suppressed plan, warming to protect the oysters, promote seedlings early hair. At present, although the soil moisture is sufficient, the soil is not solid enough, and it is windy and rainy in spring, and the amount of evaporation is large. The soil should be repressed in a timely manner, that is, the soil should be buried, the cracks must be reduced, and the evaporation should be reduced to ensure the water nutrient around the root system and promote root growth. Immediately after the suppression, the plan was taken to achieve Panasonic's effect, ensure warming and temperature, eliminate early weeds, and strive for active management of wheat fields. Second, to promote the combination of control, classification and guidance, reasonable operational planning spring fertilizer. Spring water and fertilizer management should be based on days, place, due to seedlings, classification guidance, reasonable promotion and control, should not ignore the seedlings to follow suit management. Control and promote the combination of a good wheat field. The fertility level of a type of wheat is higher, and the number of stems per mu is 800,000-900,000. The spring management should control the integration, reduce the invalid tillering in spring, control the internode length, increase the spike formation rate of pre-winter taro, and increase the number of panicles. Spray Zhuangfengan and other regulators during the start-up period, and conduct the first fertilizer and water management during the jointing period. Combine control and promote good control of two types of wheat fields. The number of mu stems in the second category of wheat is 600,000-800,000. Spring management should promote spring tillering and improve tiller success rate on the basis of consolidating the pre-winter tiller, but pay attention to controlling the number of tillers and the length of the internodes. The first time the fertilizer and water management started in the jointing or jointing period, about 20 kg of urea was topdressed. In order to control, Wang Miao turns strong seedlings. Prosperous long wheat stems with more than 900,000 acres, higher plants, longer leaves, the spring management should be dominated, rejuvenated in the green period and timely seedlings, spray Zhuang Fengan and other regulators to get up, so that Wang Miao turns strong. Fertilizer management shall be carried out as appropriate. If there is any defertilizer or frost damage, the Wangmiao wheat field shall carry out the first fertilizer and water management in the beginning stage, and 15 to 20 kilograms of urea shall be topdressed; no fertilizer or frost damage shall be carried out for the first time during the jointing stage. Management, acres of topdressing urea 15-20 kg. To promote the main, so that weak seedlings turn strong seedlings. The three types of weak seedlings and wheat fields are mainly dumped plots. The number of mu stalks is less than 600,000. There is no tiller or 1 pod, and it is difficult to reach the appropriate number of mu. The spring management promotes early spring and long delivery. , to increase the percentage of spikes. Fertilizer management should be carried out in two stages. For the first time, when the 5 cm ground temperature is stable at 5°C in the returning green period, about 10 kg of urea can be topdressed (if there is rainfall, fertility can be applied without rain, and no watering). After watering, As early as possible planning, increase the temperature; the second fertilizer in the jointing period, and then topdressing urea about 10 kg per acre. Third, do a good job forecasting pests and weeds, do a good job of comprehensive prevention. Due to the high temperature, heavy rainfall and heavy weeds before the winter, we must strengthen the chemical weeding work after returning green, and pay special attention to forecasting and timely prevention and control of diseases and insect pests such as broad-leaved weeds, sheath blight, red spider, and midge. . Broad-leaved weeds. Mainly is the Artemisia halodendron and leeks, in addition to returning to the middle of the cultivation of grass, the best chemical weeding. Before the jointing of wheat, spraying with tribenuron-methyl herbicides to spray water, such as using 75% of superstars 1-1.5 grams or 10% of tribenuron-methyl powder 10-15 grams of water spray. It is important to note that during the control period, the period of use of herbicides is usually during the period of returning to the beginning of the growing period; in strict accordance with the use concentration and technical operating procedures, pesticides should be adjusted by the secondary dilution method, and the pesticides should not be re-sprayed or missed in order to avoid phytotoxicity. 2,4-D butyl ester is easy to produce phytotoxicity to cotton and other dicotyledonous crops. Even after the drug is used, it has residues of pesticides and re-sprayed cotton and other crops also have phytotoxicity. In the cotton and peanut fields, weeding is not to be used as far as possible. 4-D butyl ester. Sheath blight. It can be used in wheat to jointing period with 12.5% ​​diniconazole 20-30g or 20% Jinggangmycin Bacillus cereus (stripe mildew) suspension 60-100ml, 60-70 kg of water, spraying Wheat stem base. Red spider. Mu 40% omethoate 25 ml of water 30-40 kg, or 1.8% avermectin 3000 times spray control, can treat L. striacae, prevent bush dwarf disease. Midge. Toxic soil control in flood season: In late April (early end of booting period), use 5% chlorpyrifos powder 600-900 g or 3% methylhexadiosal powder 2 kg to make up 25-30 kg of poisonous (sand) soil. The ridge is evenly applied to the ground surface; watering after spraying is more effective. Adult stage foliar spray control: In early May (heading period), mu with 4.5% of cypermethrin EC 40 ml or 10% imidacloprid WP 15g, 50 kg of water spray, can control aphids at the same time. Chemical control and prevention. Before and after the period of getting up, use 20% of Zhuangfengan EC 30-40 ml or 15% of paclobutrazol 30g, spraying 40 kg of water on the foliar to prevent lodging in later stages.
