In the context of the current high pork prices, the demand for vegetables and fruits has begun to rise. In this context, it is more important to ensure the quality and safety of vegetables and fruits. At present, the majority of vegetable growers have fully realized the harm of pesticides, and even the economic price of green vegetables is higher. Therefore, the enthusiasm for the development of green vegetable production is very high, and with the use of agricultural insecticidal lamps and other pest control technologies. It can protect the production of green vegetables and effectively improve the quality and safety of agricultural products such as vegetables. The agricultural insecticidal lamp is an advanced physical prevention and control device that uses light to induce pests and uses insects or wind suction to kill insects. In the vegetable production, the physical control technology of the agricultural insecticidal lamp has significant effects on the control of Plutella xylostella, beet armyworm, Spodoptera litura, melon, small tiger, chafer, bean wild, and tobacco budworm. In particular, Plutella xylostella, Spodoptera exigua, etc., which have high levels of drug resistance, have become the key technology for green pest control of vegetable pests, and can be applied in the production of open vegetables and facility vegetables. In the production of vegetables, the use of agricultural insecticidal lamps to control pests has become one of the effective production management methods for the development of high-efficiency, green and environmentally-friendly agriculture in the agricultural sector. By vigorously promoting and applying agricultural insecticidal lamps, not only can it be large The amplitude lowers the density of field insects in the contemporary and next generation, effectively reduces the number of pesticides used, saves labor and pharmaceutical costs, reduces environmental pollution, and improves vegetable quality. It is an important means to achieve chemical pesticide reduction. As an important green pest and disease prevention and control equipment, the use of agricultural insecticidal lamps must pay attention to methods and methods to exert greater effects. For example, in the prevention and control of vegetable pests and diseases, the use of vegetable insecticidal lamps in vegetable fields should be concentrated. Tablets; should be targeted at the medium-sized to large-scale pests of the vegetable field, such as Plutella xylostella, beet armyworm, Spodoptera litura, melon, small tiger, chafer, etc., other minor pests should not be the focus of prevention and control; As a supplementary pest prevention and control measure, light trapping should be coordinated with other pest control measures such as biological pesticides and environmentally friendly chemical pesticides according to the type and amount of pests in vegetable fields.
Aluminium Castings - High Pressure Castings
High pressure castings which we also called die casting, is a processing way mainly used for aluminium alloy material.
The parts from this processing way normally with the feature of higher density, better surface finish and dimensions consistency compared with other aluminum casting parts.
The aluminium castings are mainly used in the field of automobiles, parts of faucet, connector aluminium housing, gears etc..
Our advantage:
1. High and stable quality
2. Strict control on raw material sourcing and inspection
3. Timely feedback on any question
4. Short lead time
