Problems solved by technology

[0003] When planting plants in saline-alkali land, there are the following disadvantages: the growth of plants requires a lot of water, and fresh water is usually used for flood irrigation, and the water utilization rate is low; fresh water is relatively scarce in saline-alkali land, and relatively rich brackish water and salt water cannot be obtained. Make full use of it; plants grown in saline-alkali land do not have roots, and the growth of plants is not good

Abstract

The invention relates to a separating-restbalk limited-quantity irrigation method using a high calcium fertilizers. The method comprises the step of separating-restbalk limited-quantity irrigation. After fixed planting survival, the interval-border limited-quantity irrigation comprises the process of irrigating by adopting a mode of mixing salt water containing the high calcium fertilizer and fresh water for irrigation; the high calcium fertilizer is prepared from the following ingredients in parts by weight: 25 to 29 parts of ammonium bicarbonate, 20 to 24 parts of triple superphosphate, 18 to 22 parts of potassium carbonate, 10 to 14 parts of monoammonium phosphate, 10 to 14 parts of calcium chloride, 5 to 9 parts of chelated iron, 3 to 7 parts of potassium fulvate, 2 to 6 parts of alginic acid, 1 to 5 parts of brown sugar, 1 to 5 parts of sodium benzoate, 0.2 to 0.6 part of sophora flower bud extract, 0.1 to 0.5 part of triiodobenoic acid, 0.1 to 0.5 part of krenite, 0.1 to 0.5 part of metalaxyl and 0.1 to 0.5 part of dichlozolin.

Description

technical field [0001] The present invention relates to a limited irrigation method using high-calcium fertilizers, in particular to a limited irrigation method using high-calcium fertilizers and its application in planting amorpha fragrans in saline-alkali land, belonging to the technical field of agricultural planting . Background technique [0002] Plants of the family Amorpha fruticosa and the genus Amorpha fruticosa have dense branches and leaves, and are also nectar plants, often planted for green sale. Deciduous shrubs, branches brown, pubescent, then smooth, odd-pinnate compound leaves, lanceolate-elliptic to elliptic, apex round or slightly concave, with small apexes, base round, and glandular points. Cold-resistant, drought-resistant, humidity-resistant, saline-alkali-resistant, wind-sand-resistant, and stress-resistant shrubs can grow on barren hillsides, roadsides, river banks, and saline-alkali lands. It is cultivated in Northeast China, North China, Northwest...
