The increase of concentration and increase.If urea concentration is too low, when spraying every time the nutrient quantity of apple tree Foliage Absorption compared with
Number is sprayed, it is necessary to increase to be limited, the number of usual foliage dressing should not be typically less than 3 times, if concentration is relatively low, be applied fertilizer
Number is also more, and when large area produces, this obviously can increase the amount of labour and cost of labor.Generally when spraying, general
Concentration 0.5%-1% urea water is once sprayed, the urea water that second of spray concentration is 1%-2% after 7 days, after 7 days
The urea water that third time spray concentration is 1.5%-2%, hereafter can depending on the circumstances or the needs of the situation continue to spray.
Lifting urea concentration can reduce the number sprayed, cost of labor be reduced, still, if urea concentration mistake
Greatly, then blade can be burnt out, can also poison plant, effect is run counter to desire.Can also contain in usual foliar fertilizer potassium dihydrogen phosphate etc. its
His nutritional ingredient, if concentration is higher, will also result in blade injury.
At present, on using urea foliar fertilizer come promote crop leaf nutrient flow back, promote the research of plant growth more,
But on how to reduce foliar fertilizer using when foliage injury caused by excessive concentration research be not also a lot.
