The latest causes and control measures of litchi retting flowers

There will be large and small problems in the production process of litchi, among which retting flower is one of them, which will affect the fruit setting rate of litchi and lead to no harvest in serious cases. So what is the reason why litchi blossoms? How to prevent and cure it? Let's take a look at the detailed introduction.

First, the reason for retting flowers

1. Excessively shorten the spike of flowers, and in the production of many early and medium-maturing varieties of fruit growers, the first batch of spikes should be removed manually or chemicals should be used to kill the first batch of spikes, so as to make them grow the second batch of spikes. The reason for this is that there are more female flowers in the second batch of flower ears, and you obviously increase the fruit setting rate and increase the yield, but often because the chemicals are not available, the newborn flower ears are shorter, and these flower ears are less permeable. Retting occurs in cloudy and rainy weather.

2. In flower thinning, if all the flower buds are erased, leaving only some flowers at the top, dense flower spikes will be formed at the top, resulting in retting flowers.

3. Failure to pick the lost flowers in time in cloudy and rainy weather will lead to retting of other flowers.

II. Preventive methods

1. After the first batch of spikes are removed or after drug treatment, when the second batch of spikes grow again, timely flower thinning measures should be taken to avoid forming clustered spikes and increase the permeability between spikes.

2. During the flowering period, the fish should shake branches in time and shake off the rotten flowers in overcast and rainy weather, so as to avoid retting flowers or diseases.

III. Remedial measures

After retting flowers, we should first shake branches to remove the rotten flowers, so as not to cause other words on the same spike to rot together. If it rains when the spike is too dense, it should be rained to increase the permeability of the spike. When the retting is serious, the rotten flowers should be cut off in time, and the flowers should be thinned and foliar fertilizer should be sprayed at the same time, the new spikes will grow again soon, and the proportion of female flowers will be higher.
