Maize is a crop that needs more fertilizer, especially for summer maize interplanted with wheat. Clever catching of three fertilizers is the key to increase production.
The jointing fertilizer is generally in mid-July, with fertile manure and strong plant growth. The amount of topdressing fertilizer may account for 20% to 30% of the total topdressing fertilizer; the land with poor fertility and thin plant growth will occupy the topdressing amount. 40% ~ 50% is appropriate, to promote roots and strong stalks, build a shelf for high yield.
Prior to entering the big bell-mouth, the jacking corn was interplanted with corn in mid-August. At this time, the corn needed the most fertilizer, which was the key period for determining the size of the ear and the number of seeds, and also the peak period of corn demand. Under medium soil fertility conditions, 40-50 kg of ammonium sulfate is used in Mushi, accounting for 50%-60% of the total fertilizer, and soil fertility is high, which can account for 35%-40% of the total fertilizer, generally increasing yield by 15%-20. %.
After attacking the pollen, it can prevent premature degeneration of defertilizer and promote large spikes and grains. The amount should not be too much, control in the total amount of less than 10%, in order to avoid greedy late maturity.
