Abstract
A cultivation method based on an LED light source and used for promoting the blossoming and fruiting of tomatoes. After one week of seedling culturing, field planting and seedling recovery, tomatoes are placed in a lighting environment with an LED light source; the LED light source is a combined light source of white light, red light and blue light; and the luminous flux density of the LED light source is 290-300 µmol·m-2·s-1. By means of treatment with an LED light formulation, the number of blossoming tomatoes is increased, such that the tomatoes blossom 5-7 days early and the fruiting time is 8-11 days early, thereby accelerating the fruit production period and improving the quality of the tomatoes.
Description
本发明涉及农业栽培技术领域，尤其涉及一种基于LED光源促进番茄开花结果的栽培方法。The invention relates to the technical field of agricultural cultivation, in particular to a cultivation method for promoting tomato flowering and fruiting based on an LED light source.
番茄，又名西红柿，是管状花目、茄科、番茄属的一种一年生或多年生草本植物，原产于南美洲，在中国南北方广泛栽培。番茄的果实营养丰富，具有特殊风味。番茄内的苹果酸和柠檬酸等有机酸，具有增加胃液酸度，帮助消化，调整胃肠功能的作用；含有的果酸能降低胆固醇的含量，对高血脂症很有益处；维生素A、维生素C、维生素B1、维生素B2以及胡萝卜素和钙、磷、钾、镁、铁、锌、铜和碘等多种元素可以满足人体对维生素和矿物质的需求；番茄中含有的番茄红素具有抑制细菌、清除自由基、抗氧化等功能。近年来，人们对番茄的需求量迅速增加，栽培种植具有良好的前景。Tomato, also known as tomato, is an annual or perennial herb of the order Tubular, Solanaceae and Tomato genus, native to South America and widely cultivated in north and south China. The fruit of tomato is rich in nutrients and has a special flavor. Organic acids such as malic acid and citric acid in tomatoes can increase the acidity of gastric juice, help digestion, and adjust gastrointestinal function; the fruit acid contained in tomato can reduce the content of cholesterol and is very beneficial to hyperlipidemia; vitamin A, vitamin C , vitamin B1, vitamin B2 and carotene and calcium, phosphorus, potassium, magnesium, iron, zinc, copper and iodine and other elements can meet the body's needs for vitamins and minerals; lycopene contained in tomatoes has the ability to inhibit bacteria. , scavenging free radicals, antioxidant and other functions. In recent years, people's demand for tomato has increased rapidly, and cultivation has a good prospect.
目前，为提高番茄产量，种子改良、优质育苗、优化种植等多种方法均被广泛研究，但仍然未达到较好的技术效果。还有研究通过促进番茄提前开花和结果来提高产量，例如专利申请号为201510147345.4的发明专利通过番 茄综合栽培技术配合植物生长激素来促进开花，但存在用量大易造成畸形果的问题，需要严格控制植物生长激素的用量；又如专利申请号为201811642387.5的技术通过光照与灌溉配合的方法提高番茄产量，需要限定特定的灌溉水量以及灌溉时间，造成水资源浪费。现有技术通过促进提前开花来提高番茄产量的方法或多或少存在一定问题，也较少有技术利用番茄的喜光性专门研究光照对番茄促花保果的效果。At present, in order to increase the yield of tomato, various methods such as seed improvement, high-quality seedling raising, and optimal planting have been widely studied, but still no good technical results have been achieved. There are also studies to improve yield by promoting early flowering and fruiting of tomato. For example, the patent application number 201510147345.4 promotes flowering through tomato comprehensive cultivation technology combined with plant growth hormones, but there is a problem that large dosage can easily cause deformed fruit, which needs to be strictly controlled The dosage of plant growth hormone; another example, the technology with patent application number 201811642387.5 improves tomato yield by combining light and irrigation, which requires specific irrigation water amount and irrigation time, resulting in waste of water resources. There are more or less certain problems in the methods of improving tomato yield by promoting early flowering in the prior art, and there are few technologies that utilize the light-loving property of tomato to specifically study the effect of light on tomato flower promotion and fruit preservation.

-1，温度控制为白天26℃，夜晚18℃。
The test of the present invention is carried out in a light environment laboratory, and the tomato test material is "Tomato Micro Tom". The tomato seedlings were raised by the plug method, and when the tomato leaves grew to four leaves and one heart, they were planted in a nutrient pot, and after the seedlings were slowed down for a week, they were placed in an LED light source lighting environment for irradiation, and the LED light source was a combination of white light, red light and blue light (WRB). ), the luminous flux density of the light source is 300μmol·m -2 ·s -1 , the ratio of luminous flux density is 1:1:1, the illumination period is 12h·d -1 , and the temperature is controlled to be 26°C during the day and 18°C at night.
作为对照，本实施例设置白光(CK)LED光源对照组，其他栽培条件均相同，进行常规管理，开花后取样测定。实验结果如下：As a control, a white light (CK) LED light source control group was set in this example, other cultivation conditions were the same, routine management was performed, and sampling was performed after flowering. The experimental results are as follows:
表1 不同光处理对番茄开花和结果时间的影响Table 1 Effects of different light treatments on flowering and fruiting time of tomato
由表1可知，通过本发明所述的LED光源配方处理，使番茄提前开花5-7天，结果时间提前8-11天，加快了番茄果实生产周期。It can be seen from Table 1 that, through the treatment of the LED light source formula of the present invention, the tomato blooms 5-7 days earlier, the result time is 8-11 days earlier, and the tomato fruit production cycle is accelerated.
本发明LED光源配方处理对番茄植株生长的影响如下：The influence of the LED light source formula treatment of the present invention on the growth of tomato plants is as follows:
表2 LED光源处理对番茄植株生长的影响Table 2 Effects of LED light source treatment on tomato plant growth
由表2可知，本发明通过白红蓝组合LED光源处理，番茄植株鲜重和干重均较于普通白光处理有所增加，说明LED光源配方处理可以促进番茄的生长。It can be seen from Table 2 that the present invention through the combination of white, red and blue LED light source, the fresh weight and dry weight of tomato plants are increased compared with ordinary white light treatment, indicating that the LED light source formula treatment can promote the growth of tomato.
本实施例还测定了LED光源配方处理对番茄开花期糖含量的影响，具体结果如下：In this example, the influence of LED light source formula treatment on sugar content in tomato flowering stage was also measured, and the specific results are as follows:
表3 LED光源处理对番茄开花期糖含量的影响Table 3 Effects of LED light source treatment on sugar content in tomato flowering stage
由表3可知，LED组合光源处理可以提高番茄花中的含糖量，进而形成的番茄果实含糖量也增加，提高了番茄的品质。It can be seen from Table 3 that the LED combined light source treatment can increase the sugar content in the tomato flower, and then the sugar content in the formed tomato fruit also increases, which improves the quality of the tomato.
