In recent years, rice direct seeding technology has been widely promoted due to its labor-saving efficiency. In particular, large grain producers and planting professional cooperatives have adopted rice as their main push technology to implement rice production. The author has been engaged in agricultural technology promotion for a long time. Recently, we went to the countryside to view the live broadcast of rice and discovered that the following “five types†of fields should not promote rice live broadcasting technology:
One is to set aside wild land. For long-term land parcels, lots of weed seeds are kept in the fields due to their land reclamation. After the rice is broadcast live, weeds are more viable and grow faster. The weeds in the field are higher than the seedlings; Cong grass field. In the first quarter, although there was no shortage of land for planting, due to the previous poor management during dry farming or rice growth, weeds were overgrown and difficult to remove. This type of plot should be carefully promoted for live rice broadcasting technology; . Cold-sweeping fields refer to the very cold soaking of rice fields or the overflow of underground cold water in the fields (especially in deep hilly areas and mountainous areas), resulting in low temperature of the fields. If sown by conventional methods, the seeds cannot be normally emerged or the seedling emergence rate is low. Fields should also be cautious in promoting rice direct seeding technology; the fourth is Tiantian. In the early stage of live broadcasting, the need for water is small, and the supply of water should be increased in the later period. Because it is the view of the Tiantian, the water source cannot be guaranteed, which is not conducive to the normal production of direct-seeded rice, and it is not appropriate to promote the live rice broadcasting technology; This is what the term “fertilizer field†refers to: there are unripe organic fertilizers in the fields or plots that contain excrement in the house, or muddy and over-fertile fields behind the house, due to unfamed organic fertilizer or Excessive organic manure affects the emergence and growth of live rice, and it is not appropriate to promote the live rice technology.
It is an important mobile tool for the home rehabilitation of the wounded, sick, and disabled, turnover transportation, medical treatment, and outing activities. The Wheelchair not only meets the mobility of the physically disabled and the disabled, but more importantly, it is convenient for the family to move and take care of the sick. Allow patients to use wheelchairs to exercise and participate in social activities.
