The hybrid japonica rice 3 You 18 was listed by the Ministry of Agriculture as a new breed that was mainly promoted in 2002. Now it has become the main planting variety for hybrid rice planting in northern Jiangsu Province. The variety has excellent rice quality, lodging resistance, high resistance to stripe blight, heading In the early stage, the main peaks of the three generations of Sassafras sinensis could be jeopardized, and the maturation period is basically the same as that of paddy field farming, and the yield is high and the benefit is good. After the experiment, it is most suitable for pollution-free cultivation of cultivated rice fields in northern Jiangsu, and it is also the first choice for hybrid japonica rice and conventional japonica rice with serious diseases in paddy fields cultivated in this area. In the cultivation of paddy fields, the production of pollution-free rice is generally 9000kg/ha. The main points of cultivation are as follows: 1. The appropriate sowing specifications are planted for the whole growth period of 145--150d, in order to avoid the occurrence of three generations of the three-sputum expectorant, the valley-fall period is May 1-1-5; The sparse breeding technology cultivates the strong and beautiful storks, and the pod age is about 30 days; planting uses “thinning and big trees†and increases the activity space of fishes, shrimps and crabs by reducing the planting density, with a spacing of 33 cm and a spacing of 11.5--13.2. Cm, planting density of 75,000 holes/ha, about 2 to 3 plants per hole, ensuring that the planting of basic seedlings is 900,000 to 1.2 million plants/hectare. 2, scientific and rational fertilization in order to take into account the relationship between planting and fertilization, fertilization should master the following principles: the appropriate amount of decomposed organic fertilizer, eliminate the application of unripe organic fertilizer, less application of chemical fertilizers, balanced application of nitrogen, phosphorus, potassium fertilizer, is strictly prohibited using ammonium bicarbonate Fertilizers with excessive levels of heavy metals. In the fertiliser management, due to the fertility of this species, attention should be paid to early application of high-quality urea 450kg/ha, high-quality superphosphate 375kg/ha, and biological potash 120kg/ha, in which the clay-holding field with strong water retention capacity and basal fertilizer account for approximately 80% - 90%, about 10% - 20% of tiller; poor sand retention, 70% - 80% of base fertilizer, 20% - 30% of tiller, partial deficiency Fertilizer fields can make up organic fertilizer for panicle fertilizer. 3, scientific management of water, and promote the control of the field water level adjustment to take into account the relationship between planting, in the hot season to raise the water level, increase the total volume of water, reduce the temperature of the water, but also to ensure enough seedlings when the water. The specific water slurry management was as follows: Shallow water promoted flooding in the early stage, reaching 2.85 million to 3 million seedlings/ha after gradually increasing the water level, controlling the medium-term population, and the water lifting time was generally after June 25, the water layer did not submerge the growing stems. The second leaf sheath is the degree, and the water level in the field ditch is maintained at 30--35cm in the middle and later stages, and is maintained until the end of the aquatic product fishing. About 7 days before harvest, water was cut off and dried. 4. Scientific prevention and control of pests, diseases, pests, and weeds The prevention and control of agricultural pests is mainly based on comprehensive prevention and control of agricultural ecology, supplemented by chemical control. Pesticides are highly efficient, low-toxic and low-residue varieties, and they are banned from sensitive varieties of cultured species. Weed control methods: control of agriculture, promote artificial weed removal, remove weed seeds; biological control, for some grass, tender grass can be put into the field for farming feed; chemical control of weeds, after planting 5 - 7d, the amount of water is slightly lower than that of the surrounding field ridges, and high-efficiency, low-toxicity weed control is adopted. "Kukejin" 750g/ha is used to spread toxic soil or fertilizer, and then the water is allowed to dry naturally. This species pays attention to the prevention and treatment of false smut disease. It is treated with a high-efficiency special “streptomyces†1.5kg/ha 5-7d before the break period, and once during the break period, the amount of water and the amount of water are appropriately increased. . Prevention and control of rice borers: Agricultural control, timely irrigation and preservation of water for 5 days before the emergence of spring locusts, killing larvae; biological control: use of bt emulsion 7.5 kg/ha before the hatching of eggs 450-600kg/ha of water is sprayed in the early evening and used every other day for another 5--6d. Chemical control: spray the water with special killing 750g/ha during hatching. Control of rice white panicles in the rice breakage period with a special killing 750g/ha control 1, 5-7d after the addition of defense. Disable organic phosphorus and pyrethroid pesticides throughout the rice growing season to ensure that rice quality meets pollution-free standards.
Toilet Safety Rails
The elderly often feel helpless when going to the toilet. As they grow older, some elderly people will dirty their clothes and pants if they can't walk to the toilet, or it is difficult to squat and stand up because of inconvenient hands and feet. Most elderly families use squatting toilets. When the elderly squat to use the toilet for a long time, they tend to feel numb in their legs and feet, and stand up prone to dizziness and fall.
The appearance of the toilet Chair can provide physical support for the elderly when they go to the toilet, so that squatting down to the toilet becomes sitting on a chair to go to the toilet. In addition, the toilet chair can also be used as a tool to help the elderly get up. The toilet chair with a toilet can also be placed in the bedroom of the elderly to facilitate the elderly to use the toilet.
With the increase of age, the nervous system has aged. When you need to go to the toilet, you often get your clothes dirty when you can't walk to the toilet. In the face of this situation, it is recommended that the elderly use a toilet chair that combines a bedpan and a hollow toilet chair. It can be conveniently placed in the bedroom of the elderly. After use, it can be covered without making the elderly panic for internal anxiety. And in winter, the elderly no longer need to worry about catching cold because of going to the toilet.
