I. Suitable scope for extension: this technology is suitable for dissemination in the districts of dongshan and the district of the main valleys of jinmei district, and in the district of the pagawa hills。
Objectives require that the application of this technology achieves the objectives of green, non-hazardous product quality standards and increased production, savings, reduced labour intensity of farmers and increased productivity of inputs。
Technical mechanisms
Pyrochemical intersorption techniques are based on the fact that grain seed grains are too small, with low pyrotechnic power, that single seed seeds are difficult to secure seeding from the topsoil, and that they need to be lumbered to produce seedlings. The seedlings of the mnd formulations for the treatment of cereals begin to die gradually in soil or during the second leaf, leaving the normal seedlings in order to achieve the cultivation density requirement in the field without the need for a seedling or seedling。
In accordance with the production requirements of the different regions, inter-comparison seedlings are produced, and farmers may choose inter-comparison seedlings that are suitable for matching, depending on the local planting density requirements, acreage volume, acreage and soil mass. At present, the cereal ratio is 50 per cent: 50 per cent。
Iv. Technological characteristics of graination control
(i) there are no special requirements for varieties and seeding periods in the graination control technique, and what varieties are needed for production and what varieties can be formulated for intercreasing control. It is also available in both spring and summer areas。
(ii) pyrochemical intersorption techniques are simple and easy to replicate, and farmers need only buy intersorption seedlings to sow and manage them in a routine manner. (iii) the application of shigei technology for the control of grains is cost-effective. The application of this technology has made it possible for the farmers to avoid heavy inter-sortage work, with three of the original acre-based workers saving one, two of the acre-based workers saving about $80 per acre for each worker. The application of grainization-controlled intersorption techniques is conducive to the breeding of seedlings, which, after seeding, can be established in two leaves, some 15 days before the normal seedlings, avoiding the seedlings and reducing unnecessary nutrient waste. In recent years, a multi-point survey has been carried out to increase the ratio of fields in the grain chemical control field by 3 to 4 centimetres, by 1 to 2 centimetres in length, by 0. 1 to 0. 2 centimetres in length and by 0. 6 to 0. 8 grams in size in single ears and by 0. 1 to 0. 2 grams in weight in thousands of grains. Average acre production increased by 18. 6 to 29. 3 kg in comparison, by 4 yuan per kg and by 80 to 120 yuan。
(iv) validation and testing of mnd formulations for the control of seedlings in valleys for a period of 30 to 50 days will not have an impact on the growth of the ground crop, and grains produced in the field are normal seeds and thus do not become pharmaceutical contamination. Its production is safe and reliable。
V. Elements: the first is that the soil must be sowed in good quality, that the earth must be soothed, that shallow tillage must take place a week before planting, and that it must then be sowed, bearing in mind that the soil cannot be planted. Second, the soil is full. On the basis of a well-prepared spring, the planting of seeds is expected to take place in time for rainfall, which can be delayed appropriately if the rainfall is low and the condition is poor. The third is that sowing be even and spread properly. In order to increase and reduce seedage, as appropriate, in accordance with soil conditions, and to avoid loss of saplings and creeps, it is important that this be followed by serious pressure to prevent the suspension of dead seedlings due to soil hysteria, which results in saplings. Four is for foot fatting. In particular, there is a need to increase farm fertilizer with nitrogen, phosphorus and potassium fertilizer. It should be accompanied by the application of advanced practical planting techniques such as integrated pest management, chemical weeding and scientific management, so that the production of quality cereals is truly a pillar of the rich in the city, leading to and facilitating the rapid development of the rural economy in the city。
