发帖数: 306 | 4 果树用那种肥比较好。这是网上的一段：
Most people don't know that fruit trees need different fertilizer than other
types of trees. Most trees get a fertilizer with a 4-1-1 ratio of nitrogen,
phosphorus, potash. But giving that much nitrogen to a fruit tree will
encourage it to put out a tremendous flush of vegetative growth with very
few flowers and not much fruit.
A low nitrogen 1-1-1 or 1-2-1 ratio is better. Ideally, the nitrogen
component should be half water insoluble, or slow release, and half water
soluble. Water-insoluble nitrogen breaks down slowly and feeds the tree over
a period of months. Compost or horse and chicken manure are great slow
release fertlizers. Water-soluble nitrogen breaks down all at once when it
comes in contact with water and gives the tree a quick spurt.
另一个说，
The first year the fruit tree is planted, fertilize it with a balanced
fertilize 4 different times. In April, May, June and July, apply 1 cup of 10
-10-10 to your fruit tree. Scatter the cup of fertilize around the fruit
trees in a 2 foot circle, being careful not to get the fertilize on the
trunk of the fruit tree.

10:10:10=1:1:1
当然后一个可操作性好。果艺也不是rocket science 差不多就行 实践中还要看效果微
调 不是完全play by book

如果直接放在土表，是不是有肥效损失
