Description
Technical Field
The invention relates to the technical field of large cherry cultivation, in particular to a technical system for promoting differentiation and development of large cherry flower buds.
Background
The large cherry is native to the Caribbean sea of West Indian Islands in tropical America, and is called as West Indian cherry or large cherry or sweet cherry. Is suitable for growing in tropical and subtropical areas with abundant rainfall, sufficient sunshine and proper temperature, is famous for the world as being rich in vitamin C, and is a world-recognized king of natural VC and a life fruit. Twigs are grayish brown, twigs are green and have no hair or are thinned and molted, and winter buds are oval and have no hair. The cherry is not barren, has poor waterlogging resistance, is afraid of drought, is not prone to strong wind, is early in flowering phase, is easy to freeze, is low in management labor, investment cost and economic benefit, and is suitable for cultivation in Shandong, Liaoning, Anhui, Shaanxi, Henan, Hebei and the like. Since large cherries form flower buds in the last year, flowers and fruits in the second year, and the amount of the flower buds formed in the last year, the differentiation quality of the flower buds influences the yield of cherries in the next year. However, fruit growers often neglect management in the last year of flower bud differentiation and lack a systematic matching technical system, so that cherry flower buds are formed in small quantity and poor in quality, and the phenomenon that the flower quantity is small in the second year or half of a full tree is caused, and therefore a set of technical system for promoting large cherry flower bud differentiation and ensuring flower bud differentiation quality is researched.
Disclosure of the invention
The invention aims to provide a set of technical system for promoting the differentiation of large cherry flower buds and ensuring the quality of the flower buds so as to solve the problems of low flower bud differentiation rate, small fruiting amount and low yield of large cherry trees.
In order to achieve the purpose, the invention provides the following technical scheme: a technical system for promoting the differentiation and the development of large cherry flower buds is suitable for a cherry garden taking Meizao, Brukas and Samituso as main cultivars, and specifically comprises the following cultivation techniques:
(1) selecting rootstocks, and selecting dwarf rootstocks such as Gisela No. 5 and Gisela No. 6; or half dwarfing rootstock and the like, so as to be beneficial to regulating and controlling the flower bud differentiation of the saplings and entering fruit early.
(2) The tree form selection and trimming technology adopts an improved spindle-shaped or fine spindle-shaped tree form. Planting 2-year-old seedlings with the height of more than 2 m, culturing enough main branches in the first year after planting by combining main stem carved buds and picking buds, and striving for about 15 branches formed in the current year; opening the angle in time, using a toothpick or a branch puller to help open the base angle before the branches are hardened in spring, pulling the branches to 90 degrees in autumn, and pulling the strong branches to 110 degrees; continuously cutting buds of the trunk in the second year, culturing upper main branches and supplementing lower branches; and bud carving is carried out on the lateral branches by carrying out interval bud carving on the lateral buds and the bottom buds. 7-8 leaves are reserved for pinching when the back upper branch grows to be about 10 centimeters, then the back upper branch grows to be picked again, the formation of flower buds is promoted, the pinching is carried out when the side branch grows to be about 15 centimeters, and the formation of long bearing branches is promoted; and (3) carrying out opening angle and branch pulling treatment on the main branches in the second year, spraying PBO (para-phenylene benzobisoxazole) which is about 200 times of the main branches in the second year for proper control, and promoting bud formation, wherein the spraying time is in the middle and late 5 months.
(3) Covering grass and covering film, and uniformly spreading the grass under the tree crown after rain or irrigation. After fertilization and watering in spring, plastic films are covered under the tree trays.
(4) And (3) water management, namely, water can not be lacked in the differentiation period of the sprouting flower buds, but the sprouting period can not be flooded by large water, the watering amount is small, and the degree of the water passing through the dry ground skin is taken as the degree for promoting the differentiation of the flower buds.
(5) Fertilizing management, namely applying enough base fertilizer to the cherries, applying the base fertilizer early, generally applying the base fertilizer before the end of 9 months every year so as to be beneficial to the development and absorption of new roots in the current year, storing enough nutrition and ensuring the differentiation requirement of flower buds in the next year;
and (3) applying a compound fertilizer before germination, requiring the most phosphate fertilizer in the flower bud differentiation period, and promoting flower bud differentiation and development by applying phosphate fertilizer in soil and supplementing monopotassium phosphate to leaf surfaces. The trees entering the fruiting period need heavy phosphorus and potassium fertilizers in the flower bud differentiation period, and flower bud differentiation is promoted on the premise of ensuring fruit growth; after fruits are harvested, additional fertilizer for the confinement is applied in time, and the bio-organic fertilizer is mainly used; timely topdressing the roots, spraying the mixed solution of 0.3 percent of urea, 0.1 to 0.2 percent of borax and 0.2 to 0.4 percent of monopotassium phosphate in the full-bloom stage to promote the fruit development and flower bud differentiation.
(6) And (3) preventing diseases and pests, clearing the garden in 3 months, and ditching and burying weeds, fallen leaves and the like on the ground underground to eliminate overwintering disease and pest bacteria sources. Before germination, spraying 3-5 degrees of lime-sulfur mixture, preventing and controlling diseases, and preventing and controlling the damage of Grapholitha molesta Busck in 6-7 months; preventing bacterial perforation and brown spot in 7-8 months, preventing early leaf drop, promoting nutrition storage in the same year, and facilitating flower bud differentiation in the next year.
Compared with the prior art, the method has the beneficial effects that: according to the method for promoting cherry germination and differentiation, dwarfing stocks, spindle tree shapes, 2-year-old seedlings are planted, the growth and flower promotion are realized through measures such as bud carving, branch pulling and pinching, the storage nutrients are enhanced through reasonable fertilizer and water management and timely pest and disease prevention, the flower bud differentiation and development are promoted, the low temperature is guaranteed through grass covering and film covering, the nutrients are supplemented, the flower buds are promoted, and meanwhile, fertilizer and water is sprayed after fruit picking, so that the method is beneficial to fruit tree nutrition accumulation, the tree body is recovered, the later period of convenience is brought for germination, differentiation and development, the germination, differentiation and the development quality of cherry trees are effectively improved through the design, and the yield of the cherry trees is improved.
