The nutrient per 1000 kg of fresh green manure is equivalent to 7-8 kg of urea, about 5 kg of phosphate fertilizer, 6-7 kg of potash fertilizer and some trace elements; green manure also contains 10-20% of organic matter, which is to fertilize soil fertility and improve the quality of cultivated land. The best organic fertilizer; green manure can also be used as a green feed for livestock and poultry, is a high-quality feed for the production of green livestock and poultry products. Pay attention to the following points in production:
(1) Variety selection. Green manure production includes the traditional green manure of Ziyunying, including economic green manure such as silkworm peas, ryegrass and peanuts. The standard farmland newly planted in mountainous and semi-mountainous areas can demonstrate the pioneering of planting yellow bud, big pod pea, soybean or silk pea. Crops can be flexibly selected according to crop and site conditions. Ziyun Ying focuses on the promotion of Ningbo Bridge species (late flower species), Anhui Gejiang species, and Yujiang species (medium flower species).
(2) Sowing at the right time. In order to keep the symbiotic period of late rice and Chinese milk vetch in 40 days, the Chinese milk vetch is usually planted after the late rice in early September, and the planting is finished at the latest on October 10. The mountain and semi-mountainous areas can be planted early. Sowing too early, the rice symbiotic period is too long, the seedlings are thin; when the sowing is too late, it is susceptible to freezing damage, and the wintering seedlings are insufficient. If sowing in the growing hybrid late rice field, it should be planted 20-25 days before the harvest of late rice, which is beneficial to the maturity of rice and the emergence and growth of grass.
(3) Sun soaking seeds. Before sowing, you should choose the sunny day at noon, spread the seeds of the milk vetch for 4-5 hours, add a certain amount of fine sand rubbing after sun-breeding, and wipe off the wax on the seed epidermis to increase the water absorption rate and germination rate of the seeds. . Seeds were then incubated with 5% saline to remove diseased grains and empty mites. Then seed the seeds in 5% of the decomposing dilute urine for 6-8 hours, or put them into 0.2% potassium dihydrogen phosphate solution for 10-12 hours, or put them into 0.1-0.2% ammonium molybdate solution. Dip for 12-24 hours, remove and dry, and mix with Rhizobium or calcium magnesium phosphate to seed.
(4) Management before broadcasting. 1 Late rice fields with planned green manure must further clear the drainage ditch. For all kinds of green rice fields, before the planting, the “Ten†word ditch or “Jing†word ditch and the ditch in the field side should be opened. If the field mud is too paste, the field should be continued. , to achieve the ditch and the same, the irrigation and drainage freely, the soil is solid, the field does not accumulate water. 2 In order to ensure that there are enough basic seedlings to survive the winter, and to achieve the goal of "Winter Strong Seedlings, Chunwang Miao", the general use of 1.5-2 kg of mu (remaining seed can be reduced to 1.25-1.5 kg), must be based on the field when planting Quantitative, evenly distributed, and evenly distributed. If the seeding is too late or the seed quality is poor, the seeding rate can be increased appropriately. 3 grab the clear sowing, the seeds in the tidal field. If the paddy field is cracked by drought, the horse water should be first irrigated to make the soil moist and then sown to facilitate seed germination and cultivation of strong seedlings.
(5) Post-broadcast management. 1 Ditching: After harvesting the late rice, clear the ditch in time (promoting mechanical ditching) to ensure convenient drainage. 2 Fertilization: After harvesting the late rice, apply 400-500 kg of soil and fertilizer to add 25-30 kg of superphosphate to enhance the cold resistance and reduce the freezing damage. Increasing the application of superphosphate is an important factor in raising fertilizer with small fertilizer. Increase production measures. After the spring, apply 2-4 kg of urea per acre, look at the application of seedlings, promote balanced growth, and build a shelf for high yield. In the middle of March, you can choose sunny and warm weather, and use 15 grams of ammonium molybdate and 50 kilograms of water to spray twice, which is beneficial to green fertilizer and long-term production, and capture high yield. 3 pest control: Ziyunying mainly has aphids, leaf miners, sclerotinia and other diseases and insect pests, and timely symptomatic spray control. 4 It is forbidden to burn late straw in the field. For the harvested straw after mechanical harvesting, it must be removed or dispersed in time to facilitate the growth of grass.
(6) Temporary tillage. Green manure harvest should be mastered in the flowering period with the highest yield of fresh grass. Our county is about mid-April. It should be reasonable to use, such as excessive dosage, which will cause a large amount of hydrogen sulfide poisoning roots in the green rice field, which will make the early rice stiff. Generally, the amount of acre is 1000-1500 kg (above ground), and the excess can be used as livestock or fish feed. The green manure that grows well should be ploughed as early as possible and fully fermented to prevent the early rice from stabbing.
(7) Retention requirements for planting: Select a field with good drainage, soil with sand, medium fertility, and non-continuous cropping for planting. It is not advisable to apply nitrogen fertilizer for planting, and about 10 kg of superphosphate and 10-15 kg of ash can be added per mu to increase seed yield and quality. In the initial flowering period, 100 g of borax and 50 kg of water were sprayed to increase the seed setting rate. The ripening period of the Astragalus pods is inconsistent, and it is generally best when the seed pods are 80% black. Usually 50-60 kg of seeds per acre can be collected.

Cabinet display lighting are gaining traction among museums and galleries for several reasons, not the least of which is that they are the safest source for light-sensitive artwork. Compared to other sources, Fibre optic display produce far less ultraviolet (UV) radiation
Caring for and preserving collections is among the most mission-critical tasks a history organization is charged with. Creating a physical environment that ensures that those collections are preserved for future generations is often the most cost-effective way to address the collection as a whole. In short, it`s cheaper to make sure the collection doesn`t need to be treated for damage than it is to conduct conservation work after the damage is done.
