How to make silage?
The raw materials for making silage include green corn stalks, fresh sweet potatoes, green grass and so on.
(1) Timely Harvesting: Using crop straw silage, we must grasp the timing. Too early will affect food production; too late will affect the quality of silage. The storage time of corn stalks should be grasped from the following three aspects: First, to see the degree of maturity of the seeds, the milk is cooked early, the cooked orange is late, and the wax is cooked; the second is to look at the ratio of yellow leaves, yellow leaves, and good leaves. Half of it is too old; the third is to look at the number of days of corn growth. Generally 110 days of mature varieties are basically mature, that is to say, sowing corn is around September 10, and after the wheat is broadcast live on September 20, it should be harvested. The silage of sweet potato vines should be cut before the frost, and the cream should be taken out after the frost. In this way, it will not affect the yield of sweet potatoes but also guarantee the quality of silage.
(2) Proper drying: If the moisture content of the above-mentioned silage material after harvesting is high, it can be properly spread in the field for 2 to 6 hours to reduce the moisture content to about 65% to 70%.
(3) Transportation: After the harvested silage materials are properly air-dried, they must be transported to the grasslands in a timely manner. If the time is too long, the nutrient losses will be high.
(4) Cut short: Shortly after the raw material arrives, it should be cut short by a rake, the green corn stalk is 1 to 2 centimeters, the fresh sweet sorghum pod and the madder grass are 2 to 4 centimeters. The shorter the cut, the more pressure can be filled when filling. Robust, beneficial to the exclusion of air, shorten the time of microbial aerobic activity during silage. In addition, the short cutting of silage material is also beneficial to the subsequent silage excavation. The livestock also facilitates feeding and reduces waste.
When cutting short with a rake, in addition to grasping the length of the cut, attention should also be paid to the collection of tools such as manpower and machine equipment in order to facilitate fashion and cellar sealing.
(5) Cellar: After short-cut silage materials (corn stalks, etc.) should be timely loaded into the silo, you can take the short side of the cut to install? It is necessary to step on the right and left, and especially to note the circumference and corners of the silo.
If there are two or more kinds of raw materials mixed silage, the short-cut raw materials should be uniformly mixed into the cellar. Also check the moisture content of the raw materials. When the moisture is appropriate, hold the raw material tightly with your fingers and the fingers will show the water droplets without dropping down. If you cannot fill the whole cellar on that day or once, you can immediately cover the raw materials in the cellar with a layer of plastic film and continue to store it the next day.
(6) Capping: Although the silage material is pressed during the storage, it still sinks after a few days. This is mainly due to the influence of gravity and the reduction of the gap between raw materials. For this purpose, when silos are filled, the silage materials must be filled up to 40 cm to 60 cm above the edge of the cellar, then covered with a piece of plastic film, and then covered with a layer of 5 The short wet wheat straw or straw cm to 10 cm thick is finally compacted with soil. The thickness of the soil is about 30 cm to 40 cm. The surface is smoothed and the pit roof is raised into a hoe shape.

The main features:
1)Ideal cold light effects
Using the new LED cold light source, ensure energy saving and environmental protection and long service life up to 80,000hours and more.
The temperature increase of surgeon`s head below 1℃. LED do not engender infrared ray and ultraviolet radiation, without the temperature
rise and tissue damage caused by halogen shadowless light, also it can accelerate the wound healing after surgery, and without Radiation pollution.
With color temperature constant and soft, LED is very close to the sunshine.
1) Excellent shadowless effect
Lamp with the most scientific radian and Multi point light source design, ensure better uniform illuminance. When the lamps are partially occluded,
also can achieve perfect shadowless effect.Lamp panel radius of gyration ≥182cm, the lamp can be pulled to vertical floor, convenient to any angle illumination.
2) Excellent deep lighting
It is based on modularize method by Computer Aided Design, focused to irradiating with more beams of LED. It produces the deep lighting which beams
more than 1200cm,the illumination of center up to 180,000Lux or more, and offer the color temperature that can be adjusted from 3700K to 5000K which
is close to sunshine. Absolutely, it really reflects the color of human tissue and satisfied by all kinds of operating light needs.
3) Advanced control system
The use of liquid crystal display button control, to meet the needs of the medical staff of different patients with the brightness of the operation.
It offers illuminance memory function.
It does not effect using when a single circuit or one bulb is broken.
4) Universal suspension system
