How to protect lemon flowers and fruits? Latest technical method tutorial
Lemon trees produce a large number of flowers, and flower and fruit drop is quite serious, especially the two physiological fruit drops in April-June, which has a huge impact on yield, so measures to protect flowers and fruits must be taken. So how should lemons be protected for flowers and fruits? Let's take a look.
1. Cultivate strong fruiting mother branches
The nutritional level of the tree body is an important factor affecting lemon fruit set. When nutrition is sufficient, flower buds are easily formed; poor branch nutrition leads to poor flower bud differentiation or the formation of a large number of incomplete flowers, which will drop heavily at the bud and flowering stages. Therefore, plants in good nutritional condition are the foundation for cultivating strong mother branches, and strong mother branches are mainly cultivated from autumn shoots, spring shoots and summer shoots.
2. Strengthen fertilizer and water management
In some regions, winter is long with drought and low temperatures. When spring temperatures gradually rise, lemons begin to resume normal growth, and at this time topdressing should be done in time to promote flower bud differentiation. Fertilization should mainly use decomposed farmyard manure, diluted with water into a thin liquid fertilizer. Remember not to apply high-concentration fertilizer, so as not to damage the roots and affect the sprouting of new roots. At the same time, quick-acting nitrogen fertilizer should be supplemented in time, but the application amount of nitrogen fertilizer should be controlled to avoid excessive vegetative growth of branches and leaves, which affects flowering and budding and is not conducive to protecting flowers and fruits. In some other regions, the flowering and fruiting period coincides with the spring rainy season. At this time, attention should be paid to timely drainage to avoid water accumulation that causes root suffocation, affects the growth of new roots, and causes a large number of flower and fruit drops, which is also not conducive to protecting flowers and fruits. Conversely, when there is severe drought in spring, irrigation should be done in time to maintain soil moisture.
3. Flower thinning
Fruiting lemon trees often have the problem of a large number of flowers and a low fruit-setting rate. Generally speaking, a lemon tree with more flowers can reach 10,000 flowers per plant, with a large proportion of leafless inflorescences and a small leaf area, causing a serious imbalance in the flower-to-leaf ratio and an imbalance between the tree body's nutrient supply and demand. If bad weather occurs during the flowering period, it can easily cause serious flower and fruit drop. Flower clusters and flower buds can be thinned and retained in a planned way to reduce unnecessary nutrient consumption by the tree body, effectively regulate the flower-to-leaf ratio, relatively increase the leaf area of the tree body, and create a good environment for flower and fruit development, so that the flowers develop well and grow strongly, achieving the main goal of strengthening flowers and fruits, increasing the fruit-setting rate, and achieving high and stable yields.
