Generally speaking, lemon flowers are divided into two kinds, one is bisexual flowers, the other is male flowers. From this we can know that there is no pistil or pistil degeneration in the stamen, so it can't bear fruit and can only pollinate, while hermaphrodite flowers can bear fruit, so artificial pollination also needs to choose hermaphrodite flowers with pistil and stamen.
Artificial pollination is to transfer the pollen of pistil to the stigma of stamen. So is the artificial pollination of potted lemon. Use cotton swab, brush and other tools to dip the pollen on the pistil and place it on the stamen. It can also be said that the pollen on the surrounding pistil is artificially transferred to the stigma of the middle style.
The main purpose of pre flowering water retention is to prevent the rapid growth of branches and shoots in summer and to promote the healthy growth of plants and flower buds. In the first ten days of summer, the water supply for the plants will be reduced day by day until the first five days.
This should be done after the lemon blossoms, once a week to apply thin fertilizer, and timely pruning, flower thinning and fruit thinning. At this time, we need to pay special attention to that, generally speaking, each branch can keep one fruit.
According to the habit of lemon, it likes fat, so it is always good to apply thin fertilizer. Before the lemon plant sprouts, apply the liquid fertilizer of putrefaction, and then apply the liquid fertilizer mainly composed of nitrogen fertilizer, so as to promote the growth of branches and the germination of branches.
