February: Plum blossoms begin in the first half of February and bloom in the middle and late period. The main work arrangements are as follows: ① Generally, plum exhibitions are held in February 10-March10 every year (taking Wuhan as an example). (2) Cutting seedlings in spring will sprout when they are not alive in summer. ③ cross breeding of plum blossom. (4) Identification of new varieties of plum and record of variety characters. ⑤ Transplanting and planting plum trees.
March: Plum blossoms bloom in late March, young fruits form in the middle and late March, and leaves begin to unfold. The work in this period is as follows: ① Pruning plum garden 1 time after plum exhibition. (2) Control aphids at the leaf opening stage (be sure to spray them several times until they are eliminated). (3) The bud wiping of grafted seedlings must last until May.
April: Spring shoots begin to sprout, and the fruit enters the hypertrophy stage. The work arrangements at this stage are as follows: ① Continue to control aphids. ② Sow summer green manure. ③ Prune plum trees in Meiyuan. (4) topdressing nitrogen fertilizer (foliar topdressing) in spring. ⑤ Fertilize the 1 year-old seedlings to make them grow sturdily for budding in summer. ⑥ Meiyuan started intertillage weeding.
May: the fruit expands further, and the fruit enters the hard ripening stage in late May. The work in this period is: ① Pruning plum trees. ② intertillage weeding. ③ Spraying drugs to control leaf diseases such as anthracnose, perforation and brown spot. (4) The bud grafting of plum blossoms begins at the end of the month.
June: In early June, the fruit is fully mature and enters the yellow maturity stage. The work arrangements at this stage are as follows: ① Continue to carry out plum bud grafting and seedling raising. (2) foliar spraying fertilizer. ③ Start digging longicorn in the trunk. (4) Spraying drugs to control pests and diseases. ⑤ Harvest yellow ripe plums and wash them. 6. Do a good job of ditching and drainage. ⑦ Potted plum blossom "withholding water" promotes flower bud differentiation. 8 intertillage weeding.
July: In July, most spring shoots stop growing and flower buds undergo physiological differentiation. The main tasks of Meiyuan are: ① intertillage weeding and covering grass to prevent drought. (2) Spraying to prevent diseases and insect pests and prevent defoliation.
August: The morphological differentiation of flower buds begins or will begin in August, and we should continue to do well in this period: ① intertillage weeding. (2) Irrigation to combat drought and prevent defoliation.
September: Flower buds differentiate and flower organs are basically formed. In this period, the management of Meiyuan should be as follows: ① Planting winter green manure at the end of this period. (2) Irrigation to combat drought and prevent defoliation. (3) basal fertilizer was applied at the later stage.
June 65438+1October: June 65438+1October, flower organs continued to form, and plum trees began to shed leaves. The work in this period is as follows: ① applying base fertilizer in the first half of the year. ② Continue to plant winter green manure.
165438+1October: all the leaves of the plum tree have fallen off, and the plum tree has entered a dormant period. The work in this period is as follows: ① Sowing rootstock seeds in the first half of the year. (2) nursery seedlings, outbound or with shipment. ③ Colonization.
65438+February: plum trees are dormant, and the management of plum garden is: ① plastic pruning. The cut branches were taken outside the garden and burned. (2) Spraying 3 ~ 5 Baume lime-sulfur mixture or 160 times Bordeaux mixture to kill overwintering pests and diseases. (3) continue to complete the colonial work. (4) Nursery continues to transport seedlings, transport them abroad or follow them in.
