Paclobutrazol preparation for regulating oncidium plant type and its preparation method and regulating method

Abstract

The present invention provides a paclobutrazol preparation for regulating oncidium plant type and its preparation method and regulating method. The paclobutrazol preparation includes the following raw material formula: 1.0-1.5g PP in 1000ml preparation 333 , 0.5~1.5g C 12 h 25 NaO 4 S. 6-9g of polysorbate-80 or polysorbate-40, 60-90ml of absolute ethanol, and the rest in distilled water, prepared by heating and dissolving at 70-80°C. The plant type control method is as follows: select a plant with a full pseudobulb and a new bud, and spray PP when the new bud grows until the leaves unfold to reveal the pseudobulb 333 For the first time of preparation, when new shoots grow to 8-15cm again, spray PP 333 For the second time of the preparation, spray PP when the new sprout leaves grow again to reveal the pseudobulb 333 The preparation is the 3rd time, sprayed 3 times in total. PP of the present invention 333 The preparation has good adhesion, good plant absorption effect, easy control and control timing, and simple spraying method. After treatment, the oncidium leaves are straight and green, the pseudobulbs are full and round, the flower branches are erect, the flowers are plump, the plant type is compact, and the ornamental value of potted flowers is greatly improved. , and can be applied to oncidium potted cultivation on a large scale.

Description

【Technical field】 [0001] 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. 【Background technique】 [0002] 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 other characterist...

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]
