Corn is a crop that requires more fertilizer, especially for summer corn that is intercropped in wheat fields.  

    Jointing fertilizer is generally in the land with strong fertility and strong plant growth. The amount of topdressing can account for 20%-30% of the total topdressing amount ; the land with poor soil fertility and weak plant growth, 40% of the total amount of topdressing % is appropriate, in order to promote roots and strong stalks, to build a shelf for high yield.  

    Before the attacking corn fertilizer enters the big bell mouth, the intercropping corn is generally in August . At this time, the corn needs more fertilizer, which is a key period for determining the size of the ear and the grain size, and also the peak period of corn fertilizer. Under moderate soil fertility conditions, 40-50 kg of ammonium sulphate is suitable , accounting for 50%-60% of the total topdressing amount ; soil fertility is high, which can account for 35%-40% of the total topdressing amount , generally increasing production by 15%-20 % .  

    After attacking and granulating, the seeds are applied before pollination, which can prevent premature aging and promote the large grains of the ear. Do not use too much, controlled within 10% of the total amount of application .

STAINLESS STEEL PRODUCTS

Stainless steel is a corrosion resistant steel alloy with a minimum of 10% chromium. There are different grades and surface finishes of stainless steel produced to accommodate the environment in which the material will be implemented. Unlike carbon steel, stainless steel does not rust when exposed to air and moisture due to the sufficient amount of chromium present. The chromium creates an invisible passive film of chromium oxide that will not let oxygen attack the surface and prevents rusting of the iron base.

Yuhong Group is a stainless steel manufactory of more than 20 grades of Stainless Steel.
