Embodiment 1

[0024] An anti-seasonal longan flower urging method, using a 4-year-old Chuliang longan tree in a longan garden in Qianjia Town, Ledong County, Hainan Province as the flower urging object, specifically comprising the following steps:

[0025] S1, after the new shoots of the longan tree are stable, compound with potassium chlorate and calcium carbonate to form a compound fertilizer, and evenly drench and apply the compound fertilizer to the roots of the longan tree;

[0026] S2, within five days, carry out foliar spraying to longan tree with the first diluted solution of foliar fertilizer, until the whole plant leaf surface is evenly sprayed wet, wherein, the first diluted solution of foliar fertilizer is composed of water, a large amount of elemental water-soluble fertilizer, Potassium phosphite and a plant growth agent are prepared by mixing, wherein the plant growth agent is prepared from a paclobutrazol solution with a mass fraction of 15% and an ethephon solution with a mas...

Embodiment 2

[0035] A kind of off-season longan flower-promoting method, with the Shijia longan tree of tree age 3 years in a longan garden in Jiyang Town, Sanya City, Hainan Province as the flower-promoting object, comprising the following steps:

[0036] S1, after the new shoots of the longan tree are stable, compound with potassium chlorate and calcium carbonate to form a compound fertilizer, and evenly drench and apply the compound fertilizer to the roots of the longan tree;

[0037] S2, within five days, carry out foliar spraying to longan tree with the first diluted solution of foliar fertilizer, until the whole plant leaf surface is evenly sprayed wet, wherein, the first diluted solution of foliar fertilizer is composed of water, a large amount of elemental water-soluble fertilizer, Potassium phosphite and a plant growth agent are prepared by mixing, wherein the plant growth agent is prepared from a paclobutrazol solution with a mass fraction of 15% and an ethephon solution with a ma...

Embodiment 3

[0046] A kind of anti-seasonal longan flower-promoting method, with the 5-year-old Shijia longan tree in an orchard of Chuliang Village, Fenjie Town, Gaozhou City, Guangdong Province as the flower-promoting object, comprising the following steps:

[0047] S1, after the new shoots of the longan tree are stable, compound with potassium chlorate and calcium carbonate to form a compound fertilizer, and evenly drench and apply the compound fertilizer to the roots of the longan tree;

[0048] S2, within five days, carry out foliar spraying to longan tree with the first diluted solution of foliar fertilizer, until the whole plant leaf surface is evenly sprayed wet, wherein, the first diluted solution of foliar fertilizer is composed of water, a large amount of elemental water-soluble fertilizer, Potassium phosphite and a plant growth agent are prepared by mixing, wherein the plant growth agent is prepared from a paclobutrazol solution with a mass fraction of 15% and an ethephon soluti...

Abstract

The invention discloses an out-of-season flower forcing method of longan, comprising the steps of S1, after shoots of longan stabilize, blending with potassium chlorate and calcium carbonate to form acompound fertilizer, and spraying the compound fertilizer evenly to the roots of longan; S2, spraying a dilution of a first leaf fertilizer to leaves of longan within 5 days; S3, spraying a dilutionof a second leaf fertilizer to leaves of longan ten days later; S4, spraying a dilution of a third leaf fertilizer to leaves of longan when budding starts seven days later, so that flowers occur, wherein the dilution of the third leaf fertilizer is made by mixing phthalanilic acid dilution and potassium phosphite dilution. Flower forcing is performed on longan; flower forcing effect can be enhanced; on damage is caused to trees; flower forcing time is shortened; the method of the invention is suitable for forcing flower at any time, flower forcing rate is high, and the yield is stable.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for promoting flowering of off-season longan. Background technique [0002] Longan (scientific name: Dimocarpus longan Lour.) is a plant of the genus Longan in the Sapindaceae family. Evergreen tree, usually more than 10 meters high; branchlets stout, puberulent, scattered with pale lenticels. Leaves with petioles 15-30 cm or longer; leaflets 4-5 pairs, thinly leathery, oblong-elliptic to oblong-lanceolate, often asymmetrical on both sides; petiole length usually no more than 5 mm. Inflorescence large, much branched; pedicels short; sepals nearly leathery, triangular-ovate; petals milky white, lanceolate, nearly as long as sepals, only outside puberulent; filaments short bristles. Fruit subglobose, usually yellowish brown or sometimes grayish yellow, slightly rough outside, or rarely with slightly convex nodules; seeds dark brown, shiny, all covered by fl...
