How to fertilize seedlings

Non-pollution vegetable fertilization includes nursery period and field growth period. The use of nutritious soil seedlings is conducive to the cultivation of strong seedlings for vegetables, laying a good foundation for the high yield and quality of pollution-free vegetables. At the same time, it is also a more effective breeding measure against the unfavorable factors such as frequent rainfall in Hainan. Therefore, it is recommended that everyone use plastic seedlings or nursery bags. In the period of pollution-free vegetable nursery, Chen Li gave the nutrition soil: 60% - 70% of surface pollution-free pure soil +20% -30% organic fertilizer +02% compound fertilizer, plus 5% lime if possible ( Sterilization). 2% of carbendazim should be added 2 weeks before seedling use, and 5% to 10% of human excrement (to be decomposed) if conditional.

Biomass Fired Steam Boiler

SZL series chain grate boiler
Our company SZL type boiler is a double-drum water tube assembly chain grate boiler. The boiler proper has an upper drum and a bottom drum longitudinally arranged along the boiler center. The front of the upper drum and two sides water wall tubes constitute the boiler hearth radiation heating surface, and the tubes between the rear of the upper drum and the bottom drum constitute the convection heating surface. The economizer is arranged on the rear of the boiler,part of heat from high temperature exhaust gas generated by burning was absorbed by economizer, then the exhaust gas go through the cooling chamber,exhaust gas enters the convection heating surface to transfer heat power again, and through economizer,dust collector, finally draught by ID fan to Chimney,discharges into the atmosphere.

Core Technology:
1. Longitudinally arranged double drum
2. Airtight and uniform-pressure wind room
3. Customized combustion device
4. "Î±" type flame combustion
5. High quality aluminum silicate insulation
6. Built-in dust cleaning
7. Easy operation control system
