Abstract

The invention discloses a method for controlling yellow and caducous leaves during growing seasons of flowering almond. The method includes: 1) selecting strong and healthy flowering almond seedlings without pests; 2) selecting loose, fertile, and well-drained sandy soil, and planting the flowering almond seedlings in a sloping field; 3) transplanting the flowering almond seedlings in autumn; 4) preparing soil and digging caves one to two seasons in advance; 5) applying decomposed organic fertilizers to the caves when planting the flowering almond seedlings, and soaking roots of bare-rooted seedlings in a rooting powder solution or irrigating the roots with the rooting powder solution; 6) irrigating the flowering almond with water for sprouting once in a sprouting period at the beginning of March per year, and top-dressing the flowering almond after flowers fall; 7) spraying lime sulphur in spring; 8) alternatively spraying Bordeaux mixture liquid and carbendazim or spraying chlorothalonil liquid, when a leaf spot disease appears; and 9) spraying pepper water or nicotine matrine emulsifiable concentrate when aphids or red spiders appear. According to the invention, agricultural practices and chemical control are combined, so that the flowering almond plant grows strongly and has luxuriant foliage, and all the kinds of diseases and pests in leaves are effectively controlled.

Description

technical field [0001] The invention relates to the technical field of cultivation and management of garden trees, in particular to a method for preventing and treating yellowing and early fall of leaves in the growing season of elm plum. Background technique [0002] Yuyemei is an early spring flower native to my country. It has dense branches and leaves, colorful flowers, long flowering period, strong adaptability, and strong salt-alkali resistance. It is widely used in gardens and is an important greening and flowering shrub species in my country. It can be planted alone or in clusters as solitary ornamental flowers and trees, planted as flower hedges or hedges, potted plants or cut flowers. The elm leaf plum used in outdoor cultivation will have a large number of scorched leaves, yellowing and shedding after entering summer, which will seriously affect the ornamental effect after flowering, and also have a significant negative impact on the flowering quantity and flower...
