As we all know, the market price of amino acid foliar fertilizer is very high, and many farmers are discouraged due to price problems. Is there a way for people to use cheap amino acid foliar fertilizer? The answer is yes. The Jinbao Microbial Fermentation Agent developed by Beijing Huaxia Kangyuan Technology Co., Ltd. can ferment soybean powder into amino acid foliar fertilizer. The foliar fertilizer can be quickly absorbed by crops, and has a significant yield increase effect on various crops. At the same time, there is also the role of improving product quality. Moreover, the most important point is that the cost is small and the operation is simple.
There are two methods for fermenting soybean powder into amino acid foliar fertilizer (liquid state) with Jinbao microbial starter: one is fermentation by fermentation tank or shaker, which can be called “foreign methodâ€; the other is utilization Cement pool or large tank, adjusting the air, temperature, moisture, artificial accumulation fermentation method, can be called "simple method", also known as "soil method", the soil method is more widely used.
The operation flow of the simple stacked fermentation method is briefly described as follows:
1. Prepare the container. First prepare the cement pool or large tank required for fermentation.
2. Prepare raw materials. The weight of the soybean powder for fermentation was weighed and the water content was measured, and the water content was generally 12%.
3. The dosage of the bacteria. Press, 1:100 ratio, that is, 100 kg of soy flour, mix 1 kg of gold baby microbial fermentation bacteria, must be stirred evenly, this process can be called inoculant inoculation.
4. Add water to the material. Add sweet and sour water to the soy flour inoculated with the bactericide (the method of making sweet and sour water: 5% brown sugar water and 3% rice vinegar can be added to the required water content), and adjust the water content of the soybean powder material. To 55-60%. Adjustment method: 100 kg of soy flour with a moisture content of 12% itself has about 12 kg of water, and then add 48 kg of sweet and sour water, totaling about 50 kg.
5. Place the bacteria. The moisture content of the soy flour material will be adjusted and naturally left for 12 hours. This process can be called "stem bacteria".
6. Start fermentation. The naturally placed material to be fermented is moved to a cement pool or a large tank for fermentation in time. In order to ensure ventilation, the thickness of the pile is generally not more than 50cm. After the accumulation is completed, the top is covered with gauze or plastic cloth, and attention is paid to heat preservation, moisturizing and cleaning.
After the start of fermentation, the fermentation temperature should be kept above 20-25 °C for 7-10 days. When the cumulative fermentation temperature reaches 300-400 °C, it can be turned over once. After the flipping, cover the cover immediately, and let it continue to ferment until the accumulation. The fermentation temperature reaches 600 ° C or above (20-25 days), the fermented material is agglomerated, the odor is basically disappeared, the fermentation can be stopped, the fermented material is turned over in time, and dried for one day (water content is 40-45%);
7. Soak extraction. The dried fermented material is transferred to a container and soaked with 5% brown sugar water to extract the amino acid water. Soaking ratio is 1 kg of soy flour plus 5% brown sugar water 5 kg, soaking time is 5-15 days, soaking is completed (no odor, liquid is dark brown), should use vacuum Pump to extract amino acid water in time, do packaging, in the shade Just keep it.
The amino acid fertilizer fermented with soybean powder can be used as a seed fertilizer or a root fertilizer in addition to foliar fertilizer.
With the continuous development of drilling production, the use conditions of drilling rigs have become more and more diversified, and various types of drilling rigs have appeared accordingly. Factors affecting the type and composition of drilling rigs include drilling method, drilling depth, borehole size and drilling tool size, and drilling area conditions (such as electricity or fuel, transportation, and meteorological conditions).
1. According to drilling method
(1) Impact drilling rigs, such as wire rope impact drilling rigs (drilling rigs), vibration drilling rigs, etc.
(2) Rotary drilling rigs, such as those used in rotary drilling.
(3) Downhole power drilling tools, such as rotary drilling tools, turbo drilling tools, screw drilling tools, electric drilling tools, etc.
2. Divided by drilling depth
(1) Ultra-deep well drilling rig. It adopts a drilling rig with a diameter of 114 mm drill pipe, a nominal drilling depth range of more than 7000 meters, and a maximum hook load of more than 4,500 kN.
(2) Deep well drilling rig. The drill rod is 114 mm in diameter, the nominal drilling depth is 4000-7000 meters or more, and the maximum hook load is 2250-4500 kN or more.
(3) Drilling rigs for medium and deep wells. It adopts a drilling rig with a diameter of 114 mm drill pipe, a nominal drilling depth range of 1500-4000 meters or more, and a maximum hook load of 900-2250 kN or more.
Three, according to power equipment
(1) Diesel Engine-driven drilling rigs, which use diesel engines as power through mechanical transmission or hydraulic transmission.
(2) AC driven drilling rig, suitable for use in oil fields with industrial power grids.
(3) The drilling rig is driven by direct current, and the working unit is driven by a direct current motor.
Fourth, according to the driving mode
(1) Drive alone. Each working machine is driven by generators of different sizes, which are mostly used for electric drive. The transmission is simple and easy to install, but the power utilization rate is low and the total equipment mass is large.
(2) Unified drive. The three working units of drawworks, drilling pump and turntable are driven by the same power unit. Most drilling rigs use this scheme. The unified drive can also include only one drilling pump, and the other drilling pump is driven separately. The unified drive drilling rig has high power utilization and can be adjusted mutually when the engine fails, but the transmission is complicated, installation and adjustment are troublesome, and the transmission efficiency is low.
(3) Group drive. The combination of power is between individual drive and unified drive. There are two options for three working machines. The power utilization rate of this kind of drilling rig is higher than that of a single drive, and the transmission ratio is simple to drive in a unified manner. Two sets of working machines can also be installed on different heights and scattered sites.
