Hedge-wall-type navel orange planting method

Abstract

The invention discloses a hedge-wall-type navel orange planting method. The method comprises the steps of land selection and soil preparation, digging of field-planting pits, treatment of the field-planting pits, planting of nursery stocks, shaping and pruning, daily protection and the like. By means of the method, breakthrough is made in innovation of planting of naval oranges, and fruit trees are correspondingly pruned respectively in the four time periods after sprouting of spring twigs in the first year, after sprouting of spring twigs in the second year, after sprouting of spring twigs inthe third year and after fruit bearing of mother branches in the third year. Planting is conducted in the mode of focusing on culturing trunks and selected branches of the fruit trees, then the trunks and the branches are fixed through supports, the height of the single trunk is reserved and increased transversely, and a certain number of branches are longitudinally reserved hierarchically and guided in growth; through centralized fruit bearing of mother branches of the branches, the row spacing and the line spacing for planting the naval oranges are reduced, the planting density is increased, and the yield of the planted navel oranges is then increased; meanwhile, the navel oranges planted by means of the method are very convenient to pick, and the method is very suitable for mechanizedwork and meets the industrialized production requirement nowadays.

Description

technical field [0001] The invention belongs to the field of fruit tree planting, and in particular relates to a fence-type navel orange planting method. Background technique [0002] Navel orange, formerly known as sweet orange, is also known as yellow fruit tree, orange, navel orange, fragrant orange or orange. It belongs to Rutaceae, Rutaceae evergreen small tree, with glabrous branchlets and short or no thorns. Leaves elliptic or ovate, entire or with blunt teeth; petioles with narrow wings and joints at the top. Navel oranges are different from ordinary sweet oranges, and generally have the following characteristics: there is an umbilicus on the top of the fruit, and the whole umbilical bag is hidden inside the peel, leaving only one style at the top and exposing the umbilical cavity after the style falls off. Or expose the navel. In addition to the large sac valve in the navel orange fruit, there is also a small sac valve developed from the secondary carpel, which is...

Problems solved by technology

At present, the output and picking efficiency of navel oranges have become the bottleneck restricting the cultivation of navel oranges. On the one hand, the yield per mu of navel oranges has reached a relatively high level, and the increase in the past two years has been very small. In order to increase the output of navel oranges, we must change the existing planting mode and fundamentally increase the output of navel oranges, but this has not been realized yet; , but because the navel orange is an evergreen fruit tree, the plant height is relatively short, and the results are scattered, which also makes navel orange picking very troublesome, very unsuitable for mechanized operations, and does not meet the production requirements of today's industrialization
