After the spring, the climate gradually rises, and wheat begins to grow green and enters the most vigorous period of root, stem and leaf growth. This is a favorable period for consolidating the strong seedlings before winter and fighting for weak seedlings. The theme of wheat spring management is to promote the division, to strengthen the seedlings, and to compete for the group. In terms of specific measures, it is necessary to aim at the characteristics of wheat seedlings, lyrics and climate, and adapt to local conditions and seedlings. Use the plan to increase the temperature, protect the seedlings as the entry point, and properly operate the fertilizer. Scientific management, promotion and control. To achieve "early tube frozen wheat, suitable for weak wheat, late tube strong wheat, skillfully control Wang Mai, timely control of pests and diseases." Promote the transformation and upgrading of seedlings, and achieve high yield, high quality and high efficiency of wheat production. 1. Due to the suitable conditions of seedlings, scientific operation of fertilizer and water 1.1 Early tube cold wheat sowing early (planted before October 2), and the wheat field watered before November 10, because of the high temperature, suffocating, forming a long wheat seedlings, the temperature plummeted, causing the upper leaves to completely dry. For the frozen wheat fields that have no dead cockroaches and only the leaves are frozen, the early spring should be planned early, the buckwheat ridges are raised, the ground temperature is raised, and the wheat seedlings are promoted. In the period of getting up, 40-60 gram of ammonium bicarbonate is applied and watered to increase the tillering rate. 1.2 Suitable for weak wheat Because the quality of the soil is not good, the soil is loose, the wind leaks and causes the yellowing of the leaves at the base of the wheat, or the nitrogen fertilizer is not applied to the straw returning to the field, and the small and weak wheat fields with obvious symptoms of de-fertilization and If there is irrigated condition and no frozen water, it should be promoted mainly. In the early spring, the shovel (the depth is 2 to 3 cm is appropriate), the clear ridge and the clearing of the tree, and the pouring of the green water is carried out. Return to green fertilizer, phosphorus-deficient wheat field, 5 to 7.5 kg of compensatory diamine; general application of 30-40 kg of ammonium bicarbonate, combined with watering per mu and 15 kg of urea. 1.3 The main body of the dark tube is the one or two types of wheat on the production. The management time of fertilizer and water should be determined according to the ground force and the seedling condition. The focus of spring management is to prevent prosperous growth and promote strong seedlings. The first fertilizer should be carried out at the jointing stage or the late stage of jointing. High-yielding fields and high-quality wheat fields advocate separate topdressing. The first watering and application of urea is 17-20 kg, the second The watering is followed by 2 to 5 kg. Wheat fields with poor soil fertility or a slight lack of population can be topdressed and watered during the period of getting up. 1.4 Qiao Guan Wang Mai has good soil fertility and large population. The wheat field, which has a long trend in spring, can control the growth of aboveground and excessive tiller in the wheat greening period and the uplifting period. In the early spring, the temperature is high. It can inhibit the growth process of wheat too fast and avoid premature entry into the jointing period. For wheat fields with a tendency to sag, before the jointing of wheat, use chemical fertilizers such as Zhuangfeng amine to prevent it from falling. According to the seedlings, you can flexibly master the fertilizer and water management. If there is no fattening phenomenon, you can go to the topping stage to fill the water. If there is a phenomenon of de-fertilization, 40% to 50% of the amount of spring topdressing should be applied to the ditching water after the new leaves grow, and the rest should be applied in combination with watering at the jointing stage. At the same time, according to the ground force, the proportion of the first and second top dressing should be properly adjusted. If the bottom fertilizer is insufficient and the soil strength is slightly poor, the proportion of the first top dressing can be increased; if the bottom fertilizer is sufficient and the ground power is high, the proportion of the first top dressing can be reduced. 2. Two or three fertilizers, flexible The two or three fertilizers should be controlled according to the conditions of the seedlings, the sensation and the climate. Generally, the high-yield wheat fields, especially the high-quality wheat fields, should be watered for the second time in the flag-picking period. Combined with watering, the urea should be applied 2 to 5 kg, and the wheat flowers should be 10 to 15 After the third watering, the water will not be topdressed. 3. Do a good job in the prevention and treatment of diseases, insects and grasses In early spring, the control of wheat pests and diseases is focused on sheath blight, red spider, wheat stubble, midge, and weeds in wheat fields. According to the basic characteristics of the ecological structure of early spring wheat, the focus is on protecting and utilizing beneficial organisms in wheat fields, supplemented by agricultural control. Chemical control. The specific prevention and control indicators and control measures are as follows: 1 wheat sheath blight, the control index is that the rate of diseased plants in the field reaches 15%, and the general use of 5% of jinggangmycin 100-150 ml or 20% of powder-induced emulsifiable concentrate 50 ml 40 kg of water spray, spray again 10 to 15 days; 2 wheat red spider, the prevention and control index is 200 heads per foot, in the prevention and control of agricultural measures, combined with wheat field watering, serious sprayable Triclosan. McMug: More than 500 heads per hundred ears of wheat, 10% of imidacloprid 10g per acre, 10kg of water spray, 40% omethoate, 30ml per acre and 10kg of water spray. Wheat midge: can be used in 50% phoxim or 40% methyl ethion in the end of April, 250 grams per acre to form a poisonous sand, the control effect can reach about 90%; 3 wheat weeds, combined with wheat fields, Artificial weeding is the main method, and weeds can be sprayed with herbicides for chemical weeding. The time is from March 20th to the beginning of April. Generally, 10% of Melaleuca 8g or 90% of superstars are used. Spray 50 kg of water. 4. Timely control and anti-fall For high-stalk varieties (such as 8901) and wheat fields with risk of lodging, it is necessary to seize the key timing and timely control. Generally, the use of paclobutrazol 40g on water 20~25kg or acre with Zhuangfengan 30g on water 20~25kg is evenly sprayed before the end of the wheat jointing, so that it is not heavy spray, no leakage, and pay special attention. The dosage should be accurate to avoid adverse effects. 5. Pay attention to temperature changes in time to prevent spring frost damage Spring is prone to cold springs, causing wheat to die. Once the spring temperature is low, take measures as early as possible, try to avoid watering when cooling, and timely fertilizer or foliar fertilizer after freezing to prevent freezing damage in spring. Cosmetic ingredients are too broad a range. Our industry is usually divided into: 1. Basic ingredients, water or oil The main basic ingredients of general skin care products are distilled water or purified water, oil is vegetable oil or animal oil or mineral oil, according to the form of oil: liquid oil, semi-solid fat, solid wax. 2. Added ingredients, functional ingredients or control and adjustment ingredients Functional ingredients are mainly moisturizing, whitening, anti-aging, acne and other effective ingredients, according to different processes, plants as extracts, other organisms as extracts. Control components are preservatives, antibacterial agents, thickeners, emulsifiers, flavors, pigments and so on. Preservatives ensure that the product will not rot and deteriorate, antibacterial agents ensure that the product will not be infected by fungi, thickener to adjust the viscosity and flow variation, emulsifier to determine the product evenly dispersed into another substance, essence and pigment to ensure the stability of product smell and color.
