Cultivation method for improving salt tolerance of koelreuteria paniculata

Abstract

The invention relates to the technical field of plant cultivation, and particularly provides a cultivation method for improving salt tolerance of koelreuteria paniculata. The cultivation method comprises the following steps of (1) land selection and preparation, specifically, selecting medium-light saline-alkali soil with loose soil, good drainage and low underground water level for cultivation; (2) soil disinfection, specifically, disinfecting seedbed soil with 65% zineb powder or 50% carbendazim powder; (3) seed disinfection, specifically, carrying out disinfection treatment by using a dexondisinfectant; (4) sowing, wherein the plant spacing is 30-50 cm, and the sowing depth is 5-7 cm; (5) spraying a foliar fertilizer, specifically, after seedlings emerge, spraying the foliar fertilizeradded with salicylic acid and magnesium sulfate with a certain concentration; (6) trimming, specifically, thinning out overdense branch tips and excessive branches in time in combination with management; (7) spraying carbendazim, specifically, spraying carbendazim liquid with a certain concentration according to seedling conditions; and (8) outplanting. By adopting the method, the survival rate and the growth rate of the koelreuteria paniculata cultivated in coastal saline-alkali soil are remarkably increased, and the utilization value of the koelreuteria paniculata in coastal protective forest construction is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a cultivation method for improving the salt tolerance of eucalyptus. Background technique [0002] Luan tree is a plant of the genus Luania in the Sapindaceae family. It is a deciduous tree. Because of its tall tree shape, beautiful plant type, rich autumn leaf color and strong stress resistance, it has become a commonly used tree species in urban greening in my country. The eucalyptus has strong adaptability to the environment, likes to grow in calcareous soil, and is resistant to salt and short-term waterlogging. At the same time, eucalyptus has deep roots, strong sprouting ability, fast growth speed, and is also widely used as the main tree species for coastal shelterbelt construction in my country. [0003] my country's coastal areas have a total tidal flat area of ​​2.2 million hm 2 , is an important reserve land resource. Coastal saline soils are mostly ...
