Recently, I went to some high-yielding areas of green manure and farmers' friends to sum up the cultivation experience of high-yield green manure. Everyone agreed that the “winter strong spring†is the key to winning the high yield of green manure. The focus of field management is to protect stems and leaves branches, promote the development of root nodules, strive to survive through strong seedlings, and quickly develop strong seedlings. We must do the following five things. To open a good ditch to prevent red crocus seedlings required to grow in relatively dry soil, most afraid of field water. In some places, green manure fields have not yet been opened to deepen the drainage ditch. With the declining temperatures, freezing rain and snow is approaching, and it is imperative that good drainage channels for green manure fields be established. Not only must we open the fields horizontally and straightly, but we must also open the gutters around the area and dig out the outlet channels so that the gutters can communicate with each other and the ditch can be connected. It is also necessary to pay attention to frequent ditch clearance and prevent the accumulation of stagnant water in the fields in order to promote safflower cultivation. Grass seedlings take root and grow long leaves, and strong seedlings have a winter. In the case of dry years, white soil should be filled with “running horse water†in a timely manner to moisten the soil so as to satisfy the weed and moist characteristics of red flower grass. Irrigation and drainage should be done in order to adapt to the fertility characteristics of safflower. During the winter and early spring, the moisture requirement is moist and wet, and dry and too wet must be adjusted by drainage and irrigation. Application of phosphorus and potassium to prevent stiff red flowers and plants is a good phosphorus and potassium crops, especially after the application of phosphate fertilizer can promote root growth, enhance nitrogen-fixing ability, can play a role in phosphorus nitrogen, small fertilizer for large fertilizer. At the same time, winter temperatures are low, and there is a shortage of available phosphorus in the soil. By applying phosphorus to increase ground temperature, the general supersaturated superphosphate 20–25 kg and potassium chloride 5–7.5 kg are used; if there is no chemical potash, per acre Sprinkle 125-150 kg of plant ash. According to the experiment, applying 20-25 kg of phosphate fertilizer per gram of safflower seed field can increase fresh grass production by 80-100 kg per kilogram of superphosphate. The top-dressing of phosphate fertilizer can supply rhizobia nutrition on the one hand and phosphorus fertilizer on the other hand. After absorption, about 70% of them are stored in the plant body. After the fresh grass rots and decomposes, these phosphate fertilizers are returned to the soil and reabsorbed by crops. Therefore, the application of phosphate fertilizer to winter-green manure must not be ignored. Increased coverage of anti-freezing safflower seedlings has poor cold resistance. When the temperature drops to 3~5°C, the leaves are vulnerable to freezing injury. After the late rice is harvested, or before the arrival of the cold wave and frost, straw, grass ash, garbage fertilizer, decomposing pig cow dung, etc. can be uniformly applied to the field surface, and there is a significant effect of insulation and antifreeze. Generally, 100-125 kilograms of straw or 30-50 kilograms of ash are used per acre, or 750 kilograms of waste manure or 500-750 kilograms of pig manure. This can avoid direct sunlight on the ground, beneficial to drought, but also for the red flower grass seedlings wind block, play a very good role in the cold. The period of symbiosis between herbicide-prevented grass-eaten late rice and green manure is as long as 1 month. During this time, weeds breed more and inhibit the growth of green manure seedlings, resulting in grass shortage. Agents kill aphid and other grass weeds. The method is: When looking at Aphrodites grow to 3 to 5 leaves, use grass gram grams of 30 to 50 ml, or use the fine steady kill 50 to 100 ml of water evenly spray 50 kg. Do not spray or spray when spraying, so that the surface of the wet, can increase the weeding effect. Prevention and control of diseases and diseases Saffron diseases mainly include sclerotinia and powdery mildew. During the growing period, sclerotia should be removed from the diseased plants in time and burned with lime in the center of the disease. Powdery mildew can be sprayed with 0.4-degree lime sulfur mixture, or 1:5 sulfur lime powder can be used. Insect pests of safflower include locusts, thrips, leafminers, etc., and comprehensive control measures can be adopted, such as spraying some hay ash, etc. The effect is good, chemical pesticides can be sprayed with 2.5% enemy to kill 2500-3000 times, and the control effect is good. .
