It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention provides a flower and fruit pruning method for a citrus young tree in a flowering phase, wherein after buds of citrus emerge, the pruning for the buds and the flowers is carried out in the whole time period from the size of a flower bud and a mung bean to the fading and the shedding of petals, and the method specifically comprises the following operations:
(1) the top of the crown: firstly, cutting off the fruiting mother branches of autumn tips of more than 0.3cm from the top of a crown from the base, and only keeping weak autumn tips as fruiting mother branches; secondly, the bud-free branch groups are re-retracted and trimmed, the height of the tree crown is controlled within 2.2m, and the effects of inhibiting the top advantage and improving the ventilation and light transmission of the tree body are achieved; thirdly, only leafy flower branches and leafless flower branches within three leaves are reserved for the mother branches with few buds and fruiting, and the other branch tips are completely cut off, so that the purpose of bud occurrence is achieved;
(2) the middle upper part of the crown: the branch tips are treated differently according to the species and the thickness of the branch tips according to the principle of 'from outside to inside'; firstly, respectively processing the autumn-tip fruiting mother branches at the middle upper part of the crown according to the thickness of the base, and cutting off the mother branches from the base with the thickness of more than 0.5 cm; only keeping less than 3 leaves with leaf and branch sections within 0.5cm, and cutting off the rest parts by adopting a short shearing method; secondly, only the leafy flowering branch and the leafless flowering branch within three leaves extracted in the current year are reserved as bearing branches for the spring tip bearing mother branch at the middle upper part of the crown; thirdly, the stalk branches are processed: 99% of the carpopodium branches are cut from the base part, and only the branches with buds; the fruit stalk branches usually have leaf buds and flower buds growing together and are in a fasciculate state, so that more than 3 leaves with leaf branches and nutritional young shoots are removed;
(3) the lower part of the crown: cutting off all branch tips below 30cm from the ground, thinning out the clustered new tips, and shrinking and shearing weak branches.
It is worth noting that after buds of the citrus young tree emerge, spring shoots germinating in the current year at the top and middle upper part of the crown are all cut off, only effective flower branches are reserved, and the effect that the buds are only seen and no new shoots are grown at the periphery of the crown is achieved through the intuitive effect of bud preservation and flower preservation trimming.
It is worth noting that each tree needs to be pruned for 2-3 times with the time interval of 7-10 days, so as to achieve the obvious yield increase effect; after the first omnibearing fine pruning, the second re-pruning only needs to prune more than 3 leafy flower branches and nutritional new shoots sent out on the bearing mother branches and erase the bud of pruning openings; the third time of the supplementary shearing only needs to shear (smear) more than 3 spring shoots.
It is noted that in citrus juveniles, flowering pruning is based on fruiting mother branches, and the number of leaves of flowers extracted from the mother branches is used to determine the 'leaving and remaining' of the mother branches.
It is noted that the pruning quantity is determined according to the types (autumn tips, spring tips, fruit stalk tips) and the thicknesses of the autumn tips of the fruiting mother branches based on the fruiting mother branches in the minor years of the citrus.
The flower season pruning of the invention is the pruning of the whole time period from the bud green bean size after the citrus bud appears to fall off until the petals wither and fall off, the late and early stages and the length of the flower season are different according to the species, the variety and the climatic conditions of the citrus, and the period is about 40 days from the middle and the last ten days of 3 months to the end of the last ten days of 4 months in the state of eternal province in Hunan.
The invention provides a method for intuitively solving the problem that the flowering phase pruning step is 'from top to bottom, from outside to inside' by using a citrus tree body part decomposition method on a citrus young tree. The method regulates the contradiction between vegetative growth and reproductive growth of the citrus young trees through flowering phase pruning, controls the vegetative growth, promotes the reproductive growth, and enables the nutrients of tree bodies to be supplied to flower buds and flower organs in a centralized manner, thereby improving the flower quality, achieving the purposes of flower and fruit retention and yield increase, and under the same cultivation and management conditions, the method can improve the plant yield of the citrus by 60-90% and the high-quality fruit rate by more than 80%.
