Plant shape control PP333 preparation for oncidium as well as preparation method and control method of preparation

Abstract

The invention provides a plant shape control PP333 preparation for oncidium as well as a preparation method and a control method of the preparation. Every 1,000 ml of the PP333 preparation is preparedfrom raw materials as follows: 1.0-1.5 g of PP333, 0.5-1.5 g of C12H25NaO4S, 6-9 g of polysorbate-80 or polysorbate-40, 60-90 ml of absolute ethyl alcohol and the balance distilled water through heating and dissolution at the temperature of 70-80 DEG C. A plant shape control method comprises steps as follows: one plant with a full pseudobulb and one new bud is selected, and when the new bud growsto unfold a blade to expose the pseudobulb, the PP333 preparation is sprayed for the first time; when a new bud grows to 8-15 cm, the PP333 preparation is sprayed for the second time; when a newly growing bud unfolds blades and expose the pseudobulb, the PP333 preparation is sprayed for the third time, and spraying is performed three times in total. The PP333 preparation has good adhesion, the plant adsorption effect is good, the control and treatment time is easy to master, the spraying method is simple, the treated oncidium has upright and green leaves, full and mellow pseudobulb, upright flowers and branches, plump flowers and compact plant shape, the ornamental value of the potted flowers is greatly increased, and the preparation can be applied to potted flower culture of oncidium ona large scale.

Description

[0001] 【Technical field】 [0002] The invention relates to a plant type regulation preparation and a regulation method, in particular to an oncidium plant type regulation paclobutrazol preparation and a preparation method and a regulation method thereof. [0003] 【Background technique】 [0004] Oncidium (Oncidium) is an important species of cut flowers and potted flowers, with high ornamental value and economic value. In recent years, the market demand for potted oncidium has been increasing, and it has become an important species of potted orchid after Phalaenopsis and Cymbidium, with broad industrial prospects. my country began to introduce oncidium in the 1960s, and has formed a certain industrial scale in Guangdong, Hainan, Fujian and other places, but mainly cut flower production. Oncidium cut flower varieties mainly include 'Oncidium Gower Ramsey' (Oncidium Gower Ramsey) and 'Lemon Heart' (Oncidium Gower Ramsey 'Lemon Heart'). The technology is relatively simple and oth...

Using PP 333 There are very few studies on regulating the plant type of Oncidium, and there are reports by Peng Fang et al. 333 When treating ramet seedlings of the potted oncidium variety 'milliongolds', the height of the scape can be significantly reduced, but at the same time, the number of branch branches and the differentiation rate of flower buds are reduced, which has a certain impact on the ornamental quality of potted flowers. PP 333 Effects on plant leaf and pseudobulb morphology, also unspecified for PP 333 [Peng Fang, Wei Pengxiao, Tian Min, Cen Xiufen. Effects of spraying different growth regulators on flowering of 'milliongolds' oncidium [J]. Subtropical Plant Science, 2011, 40(3): 12-15]
