Biogas fertilizer watermelon technology
First, the characteristics: The technology is simple and easy, low cost. Using biogas fertilizers, watermelons are sweet, big, yield high, and the market is ahead of schedule.
Second, the method
1, timely sowing. In late March sowing, sowing seeds before the sun 1 to 2 days, with a plastic bag, put into the digester discharge soaking 8 to 10 hours, remove the light rake for about 1 minute, washed germination. Use nutrient soil (a biogas residue plus a piece of soil) to make nutrients.
2, Shizujifei, timely planting. Apply sufficient winter basal fertilizer, apply 2500 kg of biogas residue fertilizer per 667 square meters (1 acre), spread evenly on the surface of ridges, and then deeply plunge into soil. When planting 6 leaves, plant the seedlings. Before planting, apply 1500 kg of marsh. Slag fertilizer, according to the situation to add 50 kg of potassium, phosphate fertilizer, shallow dig into the soil.
3, do a good job in field management. Dingmiao live tree after chase 1 ~ 2 times of biogas slurry, about 500 kilograms each time, the concentration should not be too high (1 kilograms of biogas slurry against 2 kilograms of water), between the rows of facilities, melon seedlings out of the vine, reapply a fruit fertilizer, The ratio is 100 kg of cooked cake with 50 kg of biogas manure and 10 kg of potash fertilizer. After about 10 cm of ditch is opened, the first batch of watermelon is harvested. After the first batch of watermelons are harvested, the biogas slurry is diluted with dilute biogas slurry to recover fertilizer 7-7 days.
Third, suitable conditions: The technology is suitable for the county's vast rural, farm and watermelon professional households.
Laser distance measure is a very convenient tool for various types of applications in industries, construction and house decoration. Laser distance meter is a very useful device which gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, infrastructures, gardens, roads, and many other applications requiring accurate results for distance , area and volume measurement.
Trade your heavy tape measure for laser
rangefinder, which let you simply take measurements with one hand. No matter
your job, the laser rangefinder will help you measure much farther, with
greater accuracy and in more situations, saving you money and time.
