Choosing the fine varieties of autumn sowing garlic should choose varieties with wide adaptability, hi light and cold resistance, robust growth, high convulsions, and high yield of garlic bulbs and garlic sprouts.

It is the key to obtain high yield and harvest of garlic sprouts and garlic heads when determining appropriate sowing dates for timely sowing of garlic. Film covered with garlic, sowing should not be earlier, it can not be late. Prematurely, the garlic sprouts before winter and grows too profusely. It is prone to freezing damage during winter, and it will increase the number of small garlic in the center; if it is too late, it will lose its significance. Therefore, the suitable sowing date should be 7-10 days later than the non-coverage cultivation, that is, sowing in mid-October.

Fine soil preparation, give enough base fertilizer. As the saying goes, "The soil is not deep-rooted and garlic must be drilled everywhere," which clearly illustrates the importance of deep plowing. General tillage depth of 30 cm or more. Garlic field preparation should meet the requirements of "early, flat, loose, broken, net, and radon". As early as early morning thawing, early ploughing and early sun drying; flat, is the ground leveling; loose, broken, soil is loose and fine and no waste; net, there is no crop root, waste film, etc.; Foot, must be planted in the first 3 to 5 days before the cultivation of muddy water. Reaching the above requirements is the basis of good garlic.

Plastic film mulching should be applied to the base fertilizer, mainly farmyard manure, supplemented by fertilizers, nitrogen, phosphorus, potassium with the principle. In general, 5000 mu of high-quality farmyard manure and 80 kg of cake fertilizer are used. Based on the application of organic fertilizer, 50 kg of urea, 80 kg of phosphate fertilizer, 25 kg of potassium sulfate compound fertilizer and 1.5 kg of zinc sulfate are applied in combination with cultivated land. To improve the land. Plowing rakes are used to make rakes that are 70 centimeters wide and 10 to 15 centimeters high. In combination with the whole planting, 100 kg of organic bio-fertilizer is applied per acre, carefully smashed after sowing, and sown.

Reasonable sowing, scientific management Weeding before the start of the first chemical, per acre with 48% trifluralin EC 150 ~ 200 grams, 50 kg of water evenly sprayed the ground, and then grow garlic. In order to obtain high quality and high quality, we must choose garlic, which is hard, big head and garlic. Each row is planted with 4 rows, 15 cm spacing, 10 cm spacing, and 5 cm planting depth. The mulch film is a white film with a width of 80 cm and a thickness of 0.006 cm. When the film is applied, it should be tightly pressed against the surface of the skull, stretched, straightened, and flattened. The head and both sides should be compacted with soil and compacted to prevent being torn by the wind.

Immediately after the emergence of garlic sprouts rip film, after scratching, use a fine damp soil to cover the membrane hole, so that the garlic sprouts naturally grow outside the membrane. Ganoderma lucidum grows vigorously and it is prone to defertilization in the later stage. On the basis of applying base fertilizer, fertilizer should be applied in a timely manner, which can be applied by top-lifting membrane topdressing or top dressing combined with watering.

Harvest in time to ensure that the quality of plastic film covered cultivation of garlic matures earlier, generally about 10 days earlier than open cultivation, should pay attention to timely harvest to prevent the late harvest due to garlic quality. 7 to 10 days before harvest to stop watering, so as to avoid excessive garlic after harvest, garlic, large water content and affect storage. Appropriate harvest time 20 days after the garlic convulsions, the top leaves of garlic are dry and the pseudo-stem becomes soft.

Everything You Need To Know About LED Lighting


LEDs are a simple invention with huge potential to change the lighting industry for the better. Don`t know much about them? Here are three big things you need to know to get your feet under you:
1.What Does LED Stand For?

2.LED stands for light-emitting diode.


A diode is an electrical device or component with two electrodes (an anode and a cathode) through which electricity flows - characteristically in only one direction (in through the anode and out through the cathode). Diodes are generally made from semi-conductive materials such as silicon or selenium - substances that conduct electricity in some circumstances and not in others (e.g. at certain voltages, current levels, or light intensities).


1.What is LED Lighting?
2.A light-emitting diode is a semiconductor device that emits visible light when an electrical current passes through it. It is essentially the opposite of a photo-voltaic cell (a device that converts visible light into electrical current).
Did You Know? There is a similar device to an LED called an IRED (Infrared Emitting Diode). Instead of visible light, IRED devices emit IR energy when electrical current is run through them.

1.How Do LED Lights Work?

2.It`s really simple actually, and very cheap to produce, which is why there was so much excitement when LED lights were first invented!


The Technical Details: LED lights are composed of two types of semiconducting material (a p-type and an n-type). Both the p-type and n-type materials, also called extringent materials, have been doped (dipped into a substance called a [doping agent") so as to slightly alter their electrical properties from their pure, unaltered, or [intrinsic" form (i-type).
The p-type and n-type materials are created by introducing the original material to atoms of another element. These new atoms replace some of the previously existing atoms and in so doing, alter the physical and chemical structure. The p-type materials are created using elements (such as boron) that have less valence electrons than the intrinsic material (oftentimes silicon). The n-type materials are created using elements (such as phosphorus) that have more valence electrons that the intrinsic material (oftentimes silicon). The net effect is the creation of a p-n junction with interesting and useful properties for electronic applications. What those properties are exactly depends mostly on the external voltage applied to the circuit (if any) and the direction of current (i.e. which side, the p-type or the n-type, is connected to the positive terminal and which is connected to the negative terminal).
Application of the Technical Details to LED Lighting:

When a light-emitting diode (LED) has a voltage source connected with the positive side on the anode and the negative side on the cathode, current will flow (and light will be emitted, a condition known as forward bias). If the positive and negative ends of the voltage source were inversely connected (positive to the cathode and negative to the anode), current would not flow (a condition known as reverse bias). Forward bias allows current to flow through the LED and in so doing, emits light. Reverse bias prevents current from flowing through the LED (at least up until a certain point where it is unable to keep the current at bay - known as the peak inverse voltage - a point that if reached, will irreversibly damage the device).


While all of this might sound incredibly technical, the important takeaway for consumers is that LEDs have changed the lighting landscape for the better, and the practical applications of this technology are almost limitless. To learn about why LEDs might be a good fit for your business.
