A kind of cultivation method of fruit tree in saline-alkali land

Abstract

The invention relates to a saline-alkali soil fruit tree planting method. The saline-alkali soil fruit tree planting method includes steps of taking common annual branchless fruit saplings for on-ridge root-limiting secondary culturing on land with soil property approximate to that of an orchard to be built or with the salt and alkali content lower by 0-30% than that of the common land, and applying nutrient soil to control salt by mixing in a sapling growing zone; preparing fulvic acid and naphthylacetic acid soluble powder into slurry which is used for wrapping the saplings before planting; increasing nutrient using microbial nutrition fertilizer in a sapling stage and improving resistance; performing measures like salt leaching, pressing and accumulating to improve sapling salt-alkali resistance at any time by controlling water, greatly improving salt and alkali resistance of saplings by a series of salt and alkali training, lifting the saplings and planting in the orchard to be built, dipping the saplings in the fulvic acid and naphthylacetic slurry again and broadcasting super-fine calcium carbonate in sapling holes. Various measure effects are outstanding, the survival rate of the saplings is remarkably increased in the salt and alkali area, the orchard is even, and the high yield can be realized in the second to third year and the quality is high.

Description

technical field [0001] The invention relates to a method for cultivating fruit trees, which is particularly suitable for improving the survival rate of fruit trees and the uniformity of orchards under the condition of coastal saline-alkali land, and realizing rapid, high and stable yields of fruit trees, and belongs to the field of fruit tree cultivation. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. There are still many problems in planting fruit trees in saline-alkali land. The success rate of cultivation is very low. Saline-alkali land has a great influence on the growth of fruit trees, and the following problems are prone to occur. (1) The survival rate is low. Most of the causal tree seedlings are bred in a soil environment with ...

AI Technical Summary

Problems solved by technology

There are still many problems in planting fruit trees in saline-alkali land. The success rate of cultivation is very low. Saline-alkali land has a great impact on the growth of fruit trees, and the following problems are prone to occur

(1) The survival rate is low. Most of the causal tree seedlings are bred in a soil environment with sufficient fertilizer and water. They have poor adaptability to unhealthy environments and are directly planted in saline-alkali land. Due to the hazards of salt ions, fruit trees are not easy to survive.

(2) Slow growth, salt stress makes the root system poor in absorbing water and fertilizer, especially trace elements such as zinc, iron and a large number of elements such as phosphorus are fixed by the soil, making it difficult to absorb, and the nutrients on the ground branches cannot be supplied

(3) Physiological diseases are serious, iron and zinc deficiency are serious, affecting growth and fruit, causing death in serious cases, and fruits are also prone to physiological diseases, affecting storability

(4) Low output

At present, the common method of planting fruit trees in saline-alkali land is to directly plant the purchased seedlings in the saline-alkali area. The seedlings have not been adapted to saline-alkali resistance, the survival rate after planting is low, the fruit trees grow irregularly, and are prone to iron-deficiency chlorosis and leaflet disease
