At present, it is time for corn planting. Adopting the sowing method is the most effective way to save corn seed and ensure seedlings. This method uses only 1.5-2 kilograms per acre, and at the same time can effectively promote uniform, homogeneous, strong maize seedlings, reduce energy consumption, reduce mechanical damage, reduce the rate of small plants, and can increase production of 28-40 kilograms per acre. The key link is: use high-quality hybrids and pay attention to the use of high purity, good quality hybrid generation. And strictly selected, to miscellaneous, crushed, mildew, to ensure that the purity and purity of seeds are higher than 97%, while the implementation of the size of the seed sowing. Do a good job in seed treatment before sowing. Can increase the rate of emergence of 15% -20%, early emergence of seedlings 1-2 days, an increase of 64%. Before sowing, select the seeds to dry before and after noon on the sunny day, drying for 4-5 hours every day, even drying for 2-3 days. 2 Soaking. Generally used cold soaking, warm hot and human urine soaking three kinds. Cold water soaking time is about 12 hours, warm ("two open a cool" warm water, initial temperature of about 56 °C) 6 hours, people soaking the urine is to use about 7 days of human urine 25 kg watered 25 kg, soaking for 12 hours . When soaking, it is appropriate to use the soaking liquid flush with the seed. 3 drug seed dressing. The seed dressing can be seeded with a 1% seed coating agent. The bio-inoculated Si-1 bio-potash fertilizer was used for seed dressing. The amount of mu was 0.5 kg, and it was adjusted to 200 ml of water to make it thick. Such as soil zinc deficiency, zinc sulfate seed dressing can be used, 5 grams per kilogram of seed consumption. The suitable sowing date for the interplanting corn in the suitable sowing period is 7-15 days before the wheat harvest. Middle-maturing, late-maturing corn varieties or low-yield wheat crops should be early, early-maturing corn varieties or high-yield wheat crops should be late, poorly watered plots, interplanting time is mainly subject to the lyrics. Unconditionally interplanted summer live corn, stick to plant seeds, the sooner the better. The relative soil moisture content at the time of fine sowing and one-time tilling of corn planting should not be less than 70%. 2 Ditch the precise amount of on-demand, according to the average spacing of about 62 cm (planted in large and small rows, 80 cm in big rows, 45 cm in small rows), open the 5-6 cm deep seeding trenches with a hoe or plough, and use a spacing of 18-20 cm. Seed grains, about 5500 per acre, and then covered with wet soil cover. Seedling preparation and planting At the same time or later at the same time, 300-400 acre per acre will be planted in the field or in the nutrient bowl. At the time of 5-6 leaves, raise the seedlings with the soil, cut off the upper leaves of the tall seedlings by one-third, and make supplements to the ridges at the lack of seedlings. Pay attention to water filling and compaction during supplementary planting. Http://

Geogrid

Geogrid

The Geogrid including Polyester Geogrid, Fiberglass Geogrid, Steel Plastic Composite Geogrid and Plastic Geogrid.

The geogrid is a major geosynthetic material. Compared to other geosynthetic materials, it has unique performance and efficacy. Commonly used for reinforcement of soil structure or reinforcement of composite materials.

The uses of geogrid: It is suitable for embankment and embankment reinforcement slope protection tunnel wall reinforcement large airport parking lot wharf cargo yard and other permanent bearing foundation reinforcement.

The feature of geogrid:

The high strength creep can adapt to all kinds of environment soil, and can satisfy the use of high grade highway retaining wall.

It can effectively improve the locking and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.

More suitable for deep-sea operations, embankment reinforcement, fundamentally solve the other materials do stone cage due to long-term erosion by the sea caused by low strength, poor corrosion resistance, short service life and other technical problems.

It can effectively avoid the construction damage caused by the crushing and destruction of machinery and tools in the construction process.
