Late sowing of wheat sperm can produce high yield

<

Late seeding wheat has a long seedling emergence time, which occurs late at the beginning of seedling growth; seedling growth is slow, there are few overwintering leaves, and the plant height is low; the number of grains per panicle is small and the weight of one thousand grains is low. In order to seize the high yield of late-bread wheat, field management should be strengthened after emergence.

1. Top dressing. Late seeding of wheat seedlings at the third leaf tip revealed that one third of the plants had pups. To promote the formation of these early pods and the formation of spikes, the peasants should be kept as early as possible, generally 5-10 kg of urea per mu.

2. Frost protection seedlings. Late sowing of wheat plants is susceptible to freezing damage. In addition to early application of Miaofei, conditions can be combined with cultivator loose soil before the closure of the roots, apply about 2,500 kg of ash per acre to prevent seedlings, to protect the childbirth.

3. Controlled down. Late-seeding wheat returned to spring in the spring, in the case of fertilizer and water, the leaf output speed is faster, and often there will be soaring tillers, leaves prosperous, leading to poor ventilation conditions in wheat fields. Therefore, it is better to prevent the wheat seedlings from growing too prosperous during the extension period from the green period to the 1-2 basal period. It is better to gently suppress it once with a mallet before returning to the green, control the postharvest tillering, promote the growth of the big shoots, and improve the ventilation of the group. Conditions make the base of the seedlings stout and strengthen the lodging resistance. Joint fertilizer can not be applied too early, too large, and with phosphorus and potassium fertilizer, only suitable for the growth of a particularly poor plot or patch a little fertilizer, the best urea per mu is not more than 7.5 kg. For prolonged flourishing wheat seedlings, a booster can be sprayed during the jointing period to control it.

4. Spray phosphorus strong particles. In the booting stage and before and after heading, spray 2-3 times of potassium dihydrogen phosphate or superphosphate aqueous solution, spray once every 5-7 days, spray 2-3 times in total, to increase the solid, increase the effect of 1000-grain weight.

Galvanized Steel Pipes

Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle.
