Embodiment 1

[0013] After the above operation, after 10 days of germination and rooting, apply the nutrient solution every 5 days. The nutrient solution is mixed with A solution and B at a volume ratio of 1:1. Every 100L of A solution contains 10kg of calcium nitrate and 0.5 kg of iron chelate. kg, potassium nitrate 2.5kg, every 100L of liquid B contains magnesium sulfate 2.5kg, potassium nitrate 5kg, potassium dihydrogen phosphate 2.5kg, zinc sulfate 15kg, copper sulfate 3.6kg, sodium molybdate 2.4kg, adjust pH to 5.7, EC to 1.8. After entering the reproductive growth period (flower bud differentiation begins to appear), spray once a week with the 800 times solution of Huaduoduo No. 2.

Embodiment 2

[0015] After the above operation, after 10 days of germination and rooting, apply the nutrient solution every 5 days. The nutrient solution is mixed with A solution and B at a volume ratio of 1:1. Every 100L of A solution contains 10kg of calcium nitrate and 0.5 kg of iron chelate. kg, potassium nitrate 2.5kg, every 100L of liquid B contains magnesium sulfate 2.5kg, potassium nitrate 5kg, potassium dihydrogen phosphate 2.5kg, zinc sulfate 15kg, copper sulfate 3.6kg, sodium molybdate 2.4kg, adjust pH to 5.7, EC to 1.8. After entering the reproductive growth period (flower bud differentiation begins to appear), spray once a week with 1000 times of Huaduoduo 2.

[0016] Control group: cultivated with Japanese garden formula (known formula).

[0017] After 60 days of cultivation, observe and record the status of the plants in terms of leaf length and bud number.

Abstract

The invention provides a curcuma alismatifolia flower forcing method; nutrient solution used for cultivation is composed of liquid A and liquid B, wherein the liquid A includes 10kg of calcium nitrate, 0.5kg iron chelate and 2.5kg of potassium nitrate in each 100L; the liquid B includes 2.5kg of magnesium sulfate, 5kg of potassium nitrate, 2.5kg of monopotassium phosphate, 15kg of zinc of sulfate, 3.6kg of copper sulfate and 2.4kg of sodium molybdate. The curcuma alismatifolia cultured according to the method has advantages in the appearance of flowers, particularly in plant height, bract number and the like. Meanwhile the curcuma alismatifolia has bright green, large and thick blades, and is bright-colored in flower color, thus improving ornamental value.

Description

technical field [0001] The present invention relates to the technical field of the method for promoting flowering of ginger lotus, in particular to the method for promoting flowering of ginger lotus. Background technique [0002] Ginger lotus (Curcuma alsimatifolia) belongs to the genus Zingiberaceae. It is a perennial herb tropical bulbous flower with a plant height of 30-80 cm, and the flower diameter is usually higher than the leaves. There are spindle-shaped or spherical rhizomes underground, and there are two rows of opposite buds on the corm. The growth of the buds has the habit of leaning to one side, and multiple buds can be produced continuously. However, after planting in spring, the first first-generation buds usually germinate first , this bud often has 5-7 leaves, and the buds that grow later have only 3-4 leaves. The leaves of ginger lotus are oblong, with purple-red middle ribs. The inflorescences of ginger lotus are spikes. There are 7-9 semicircular green b...
