Abstract
The invention provides a method for improving quality of loquat fruit through agricultural measures. A reflective transfer film is laid on the orchard, and a suspension magnet is combined. Key enzyme for formation and degradation of main organic acid namely malic acid of the loquat fruit can be accurately and effectively controlled. In the early stage of the fruit development, activity of pecophosphate pyruvic carboxylase and NAD (nicotinamide adenine dinucleotide)-malic dehydrogenase is increased; at the most critical stage of accumulation of the organic acids, PEPC (plasma electrode pockels cell) activity in pulp can be promoted in reduction, NAD-MDH (malate dehydrogenase) activity is remarkably restrained, NADP-ME activity is remarkably activated, the malic acid is lowered in synthesis and increased in degradation amount, the organic acid in the fruit high in content of acid is remarkably reduced, and meanwhile, TSS (total soluble solid) in mature pulp is increased. With the method, TA (titratable acid) of the fruit can be remarkably lowered, the content of the TSS in the mature pulp and weight of single fruit of the mature fruit are increased, and quality of the loquat fruit is remarkably improved.
Description
Technical field
The present invention relates to a kind of method by agricultural measures improving quality of loquat fruit, belongs to agriculture field.
Background technology
Fruit organic acid content and component are to determine one of key factor of taste of fruit quality, and one of subject matter that China's Folium Eriobotryae industry is present is exactly that fruit acidity is too high.Therefore, deacidification has very important significance to improving loquat quality, harvesting ahead of time.
Cai Zongqi etc. [fruit tree, 2004（05）28-31] can promote Folium Eriobotryae to grow in Loquat Garden ground paving reflective membrane aluminium foil and aluminium film, be conducive to branch top growth, overstriking and improve fresh leaf weight.Lay reflex film, is conducive to improving the temperature in soil winter, promotes the photosynthesis of Folium Eriobotryae simultaneously, and have additional nutrients accumulation, improves fruit quality and promotes to do sth. in advance maturation.Its middle berth aluminium foil, the loquat total sugar of aluminium film, reducing sugar, soluble solid and vitamin content are above control, but its total acid content is also apparently higher than matched group, and its reason is probably that reflective membrane process time is partially long（June 20 was to 30 days April in next year）, causing in the Fruit physiology maturation deacidification phase, because reflective membrane illumination factor causes NADP-ME still to maintain compared with low activity, fruit malic acid fails fully degraded.
The content of the invention
The invention provides a kind of method by agricultural measures improving quality of loquat fruit, with reference to Magnet and reflective film process is hung, reduces fruit organic acid content, so as to improve Folium Eriobotryae mature fruit quality.
The purpose of the present invention is to be achieved through the following technical solutions：
The present invention combines the method for hanging Magnet using orchard lay reflex film, comprises the following steps that：
1) spread the reflective membrane time：The 1st physiological fallen fruit of loquat terminates latter 5～10 days to the 2nd physiological fallen fruit；
2) spread reflective film location：Reflective membrane is paved with drip；
3) hang the magnetic field time：With fruit size as basis for estimation, as fruit transverse diameter 2.0-3.0cm,
Vertical footpath hangs magnetic field when being 3.0-4.0cm；
4) permanent magnet intensity：150-450mT, with alnico magnets by adjusting and the tree crown distance corresponding magnetic field intensity of acquisition, process time is 15-25d.
Wherein described reflective membrane is polyethylene metallized film.Routine Management is carried out after process.
The present invention can accurately and effectively regulate and control the predominantly organic acid of loquat i.e. malic acid and be formed and the key enzyme degraded, such as phosphoric acid enol pyruvic acid carboxylase（PEPC）, NAD- malic dehydrogenases（NAD-MDH）With NADP- malate dehydrogenases（NADP-ME）Activity.In fruit development early stage, the method for the present invention improves sarcocarp phosphoric acid enol pyruvic acid carboxylase（PEPC）With NAD- malic dehydrogenases（NAD-MDH）Activity；In the loquat Accumulation of Organic Acids most critical stage, PEPC activity decreases in sarcocarp can be promoted, in significantly suppress NAD-MDH activity and have activated sarcocarp, NADP-ME is active, so that malic acid synthesis is reduced, degradation amount increases again, so that organic acid is significantly reduced in the high Loquat Cultivars fruit of acid content, while and improving mature sarcocarp TSS contents.
The remarkable advantage of the present invention：
The present invention is combined using orchard lay reflex film and hangs Magnet method, can significantly reduce fruit titratable acid（TA）, improve mature sarcocarp soluble solid（TSS）Content and mature fruit single fruit weight, so as to significantly improve Folium Eriobotryae mature fruit quality.
Paving reflective membrane has significant impact with Magnet is hung to fruit quality, as shown in table 1.With matched group（Matched group is referred to not spread reflective membrane and hangs Magnet process）Compare, spread reflective membrane and hang the titrable acidity of the Folium Eriobotryae mature fruit that Magnet is processed（TA）, soluble solid（TSS）Content, solid acid ratio and single fruit weight are above control, and with the significant difference for compareing.
Table 1 spreads reflective membrane and hangs Magnet to Folium Eriobotryae mature fruit titrable acidity（TA）, soluble solid（TSS）The impact of content, solid acid ratio and single fruit weight
Note：In same row, alphabetical difference person is significant difference（Duncan duncan's new multiple range methods,P< 0.05）.
