Eustoma grandiflorum cultivation method

Abstract

The invention discloses a eustoma grandiflorum cultivation method comprising the following steps: selecting field, soil working, applying fertilizer, disinfecting soil, and applying fertilizer; removing underground insects; using a single-particle-sing-hole mode to sow eustoma grandiflorum seeds into deep hole trays filled with a sowing matrix, wherein the sowing matrix is excellent in draining performance; examining seedlings when the eustoma grandiflorum seedling grows to 3cm above the ground, removing a film and transplanting the seedlings when the eustoma grandiflorum seedlings grow to 5-10cm in height and the roots grow to 8-10cm in depth; weeding when the seedlings grow to 12cm, and weeding in every two months; topdressing; timely removing top buds when the seedlings grow to 10cm. The method can improve the eustoma grandiflorum germination capacity, and the produced eustoma grandiflorum seedlings are stronger, thus improving the seedling transplanting survival rate; the anaphase growth vigor is fast, and the product quality is good; cut flower eustoma grandiflorum anaphase growth consistency is good, and the flower leaves are tidy; the eustoma grandiflorum is strong in disease resistance, thus reducing insect diseases, improving cut flow yield, and improving the economic benefits.

Description

technical field

[0001] The invention relates to the technical field of agricultural planting, in particular to a cultivation method of eustoma. Background technique

[0002] Eustoma is a perennial herb of Gentianaceae, also known as prairie gentian. The cut flower Eustoma has large and beautiful flowers. There are double-petal strains and single-petal strains. The texture of the flowers is like silk and satin, which has a Western flavor and has a long vase time. The enthusiasm of the company is also getting higher and higher, and the production area is increasing year by year. In the cultivation process of cut flowers, the propagation generally adopts sowing propagation, and the seeds sown are mainly F1 generation hybrid seeds imported from abroad, but the cultivation management process is not perfect enough.

[0003] Lisianthus eustoma seeds are small, and there are usually 22,000-22,500 seeds per gram. They are often sown and propagated. They are mainly planted indoors i...
