2 results about "Apical dominance" patented technology

The present application relates to a kind of side branch changes more main stem shape fruit tree cultivation method, its core technology is: using the top dominance of fruit tree and the characteristics of latent bud sprouting in light, a large number of germination on the transverse auxiliary main branch and lateral branch, branch thick leaf big Zhang fat, so as to realize tree vigor rejuvenation, high quality fruit yield.The present application is through two methods of pulling branch and deleting sparse, cultivate shrub fruit tree lateral branch end distance ground 60-70 cm, arbor fruit tree lateral branch end distance ground 80-120 cm, with the opening angle of ground is 0-30 degrees to form a layer of framework, and sprout 3-4 level small branches to hang fruit.The present application adopts a kind of new shaping pruning cultivation method, after 3-5 years of special cultivation management, the whole tree keeps shrub fruit tree 0.8-1.5 meter high single layer tree crown, arbor fruit tree 1.7-2.8 meter high single layer tree crown, tree crown diameter is 0.5-1 times faster than traditional cultivation method, rapidly forms high yield tree crown, realizes early fruiting, high yield, high quality yield.

This invention discloses a method and application for promoting root bending and lateral root formation in seed-sown persimmon (Diospyros kaki). This invention belongs to the technical field of persimmon seedling cultivation and bonsai material cultivation. The method includes low-temperature stratification treatment of persimmon seeds; disinfection and imbibition treatment of the stratified seeds followed by sowing in a gibberellin-containing GA3 medium; periodic artificial adjustment of the radicle growth direction when the radicle reaches 1 cm in length to induce taproot bending; removal of 1 cm of root tip when the taproot reaches 4 cm in length to promote lateral root and fibrous root germination; and subsequent hardening-off and transplanting. This invention, by regulating early geotropism of the radicle and taproot apical dominance, enables the taproot of persimmon seed-sown seedlings to form a natural bending shape and significantly promotes lateral root germination, resulting in good ornamental value, growth vitality, and promising application prospects.
