Straw fast rot technique

"301" bacterial compost
Choose a place close to the water source, the ground, and the roadside flat. For the rot of 10,000 kg of straw, use "301" bacteria 0.5 kg-1 kg, urea 5 kg (also 10% human excrement can be used). Heap-corrosion method: firstly dig a trench of 1.5 m-2 m wide and 0.2 m-0.3 m deep, and the length is not limited. The soil is placed around the trough and sealed with silt. Water the straw in the tank to make the straw fully wet, or the straw is first wetted in the puddle and then piled up. Generally, the wet straw is divided into four layers, each layer is 0.3-0.4 m thick, and "301" microbial agent and urea are sprinkled on the upper part of each layer, and the ratio is 3:3:2:2 from bottom to top. The top of the pile is in the shape of a concave disk.
Preservative composting
Choose a place that depends on the water source, the ground, and the roadside. For the rot of 10,000 kg of straw, 1.2 kg of preservative is needed, and 1 kg of preservative needs to be dissolved with 80 kg of water. The method of composting: firstly, the straw and the water are sufficiently wetted at a ratio of 1:1.7, and the dissolved preservative is evenly sprayed on the straw by a sprayer, and then the straw sprayed with the preservative is kneaded into a width of 1.5 m and a height. A pile of about 1 meter, gently tapped with a spade (do not step on the real), take the soil and mud seal, about 1.5 cm thick.
The "301" microbial agent and the preservative should be checked for heap temperature after composting. Generally, the stack temperature should rise above 50 °C after 3 days of heaping. Otherwise, the moisture in the heap is not enough, and water can be added to the top of the pile. It can be a good compost in 20 days - 25 days in summer, 35 days - 45 days in autumn.
Enzyme compost
(1) Construction of a composting pond. When large-scale centralized production, it is necessary to build a standard cement tank for cement construction. The villagers can simply compost the pool, that is, lay a plastic film on the flat ground, and piling around with nylon nets or mats to compost in the place, close to the water source. . (2) Material preparation. Straw 10,000 kg, bran 120 kg. 20 kg of calcium magnesium phosphate fertilizer, 16 kg of enzyme bacteria, 2 kg of brown sugar, 4000 kg of dried chicken manure. (3) Stacking method. First, the straw is wetted in the composting tank to make the water content reach 50%-60%, then the chicken manure is evenly spread on the straw, and the bran and brown sugar (sludge) are evenly spread on the chicken manure, calcium magnesium phosphate fertilizer and Enlarge the enzyme bacteria and mix them evenly, then spread evenly on the bran and brown sugar. Then mix well with the fork and pick it into the simple composting tank. The bottom is about 2 meters wide and the pile height is 1.8 meters to 2 meters. The top is rounded and covered with plastic film to prevent rain.

Solar Crystal Light

100LEDs Crystal Ball Solar LED Outdoor Garden Christmas Decoration Waterproof String Light.


The solar lamp is charged during the day and automatically lights up at night because there is a voltage detection circuit inside the lamp, which detects that the voltage of the solar panel is high during the day, and the detection circuit outputs a control signal to turn off the lamp, and the voltage of the solar panel is almost zero at night. , the detection circuit outputs a control signal to light the lamp. Below we introduce a simple and easy-to-make automatic control circuit for solar lamps. As long as the circuit is added with a solar panel and a rechargeable battery, a solar lighting lamp can be formed.


During the day, due to the high voltage of the solar panel, the â‘  pin of the IC is high level, the output of its â‘¡ pin is low level, the N-channel MOS field effect transistor VT is turned off, and the LED light connected to its drain does not light up. At night, the voltage of the solar panel tends to zero volts. At this time, the â‘  pin of the IC is at a low level, and its output becomes a high level. By adjusting the potentiometer RP, the lamp can be lit in a suitable light. VT can choose AO3400 SMD MOS field effect transistor in SOT-23 package.
