What kind of fertilizer is best for sand sugar orange?
1, sand sugar orange fertilization should pay attention to methods and techniques to achieve less fertilizer efficient, economical and safe. Fertilization should be avoided when the roots are buried in the vertical outside the canopy. The soil is too dry to fertilize the roots and reverse osmosis causes dehydration and root damage. The soil is too wet to fertilize, causing roots to lack oxygen and rotten roots. Therefore, fertilization should be based on the soil is not dry and not too wet. Do not apply nitrogen fertilizer, pay attention to increase the application of phosphorus, potassium, calcium, magnesium fertilizer. If the application of urea occurs at the end of the blade or in the middle of the cognac, then the orchard should be stopped, then the orchard should be stopped. Water and fertilizer such as human and animal excrement must be fully decomposed before use.
2, the principle of fertilization in spring and summer is to apply thinner to avoid lack of fertilizer or excessive fertilization. Premature and excessive application of nitrogen fertilizer in spring will make the spring shoots too long, and it will be difficult to sit on the fruit during the internodes. It is easy to prematurely sprout the summer shoots with excessive summer shoots, which will cause a lot of fruit drop. Therefore, the important measure to control excessive premature summer harvesting is that the fertilization in the spring is not enough, and the fruit preservation work is done to prevent fruit. Too much potassium, low boron, low zinc, low magnesium, low calcium, delicate branches or insufficient light are more susceptible to cracking. Fertilization in autumn and winter, one must re-apply the base fertilizer to facilitate the restoration of the sugar orange tree potential.
