Technical Field
The invention relates to the technical field of agricultural cultivation, in particular to a cultivation method for promoting tomatoes to bloom and bear fruits based on an LED light source.
Background
Tomatoes, also known as tomatoes, are annual or perennial herbs of the order tubiform florae, the family solanaceae, the genus tomato, are native to south america and are widely cultivated in south and north china. The tomato has rich nutrition and special flavor. Organic acids such as malic acid and citric acid in fructus Lycopersici Esculenti have the effects of increasing gastric acidity, promoting digestion, and regulating gastrointestinal function; the contained fruit acid can reduce the content of cholesterol and is beneficial to hyperlipidemia; vitamin A, vitamin C, vitamin B1, vitamin B2, carotene, calcium, phosphorus, potassium, magnesium, iron, zinc, copper, iodine and other elements can meet the requirements of human bodies for vitamins and minerals; lycopene contained in fructus Lycopersici Esculenti has effects of inhibiting bacteria, scavenging free radicals, and resisting oxidation. In recent years, the demand of people for tomatoes is rapidly increased, and the cultivation and planting have good prospects.
At present, various methods such as seed improvement, high-quality seedling raising, optimized planting and the like are widely researched for improving the tomato yield, but still a better technical effect is not achieved. For example, patent of invention No. 201510147345.4 discloses that the tomato comprehensive cultivation technology is matched with plant growth hormone to promote flowering, but the problem of abnormal fruits caused by large dosage exists, and the dosage of the plant growth hormone needs to be strictly controlled; in another example, the technology of patent application No. 201811642387.5 improves the tomato yield by combining illumination and irrigation, and requires a specific irrigation water amount and irrigation time to be limited, resulting in waste of water resources. The method for improving the yield of the tomatoes by promoting early flowering in the prior art has certain problems, and the method for specially researching the effects of promoting the flower and keeping the fruit of the tomatoes by illumination by utilizing the photophobia of the tomatoes has few technologies.
Disclosure of Invention
In view of the above, the invention provides a cultivation method for promoting tomatoes to bloom and fruit based on an LED light source, and aims to optimize illumination parameters for tomato cultivation, increase the number of blossoms of the tomatoes through illumination, promote the tomatoes to bloom and fruit in advance, and improve the tomato quality.
In order to achieve the purpose, the invention adopts the following technical scheme:
a cultivation method for promoting tomatoes to bloom and fruit based on an LED light source is characterized in that the tomatoes are gradually released in seedling raising, field planting and slow-growingPlacing the seedlings in an LED light source illumination environment for illumination after one week, wherein the LED light source is a white light, red light and blue light combined light source, and the luminous flux density of the LED light source is 290--2·s-1。
Preferably, in the cultivation method for promoting tomato flowering and fruiting based on the LED light source, the ratio of the luminous flux densities of the combined light source is 1: 1: 1.
preferably, in the cultivation method for promoting the flowering and fruiting of the tomatoes based on the LED light source, the tomato seedling method is plug seedling.
Preferably, in the cultivation method for promoting the flowering and fruiting of the tomatoes based on the LED light source, the tomatoes are planted in the nutrition bowls when the tomato leaves grow to four leaves and one heart.
Preferably, in the cultivation method for promoting the flowering and fruiting of tomatoes based on the LED light source, the illumination environment of the LED light source is 26-28 ℃ in the daytime, 18-20 ℃ in the nighttime, and the illumination period is 12 h.d-1。
Compared with the prior art, the invention has the following beneficial effects:
the invention discloses a cultivation method for promoting tomatoes to bloom and fruit based on an LED light source, and the method improves the flowering quantity of the tomatoes by the treatment of a special LED light formula, leads the tomatoes to bloom 5-7 days in advance, leads the fruiting time to be 8-11 days in advance, accelerates the fruit production period, and provides powerful support for the modern high-quality tomato cultivation technology.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The methods used in the following examples are conventional in the art unless otherwise specified.
The test of the invention is carried out in a luminous environment laboratory, and tomatoes are testedThe material is "Tomato Micro Tom". The method comprises the steps of growing seedlings of tomatoes by a plug seedling method, planting the tomatoes in a nutrition pot when tomato leaves grow to four leaves and one heart, slowing seedlings for one week, and then placing the tomatoes in an LED light source illumination environment for illumination, wherein the LED light source is a white light source, a red light source and a blue light source (WRB), and the luminous flux density of the light source is 300 mu mol/m-2·s-1The ratio of the light flux density is 1: 1: 1, the illumination period is 12 h.d-1The temperature was controlled at 26 ℃ during the day and 18 ℃ at night.
For comparison, this example was conducted under the same cultivation conditions as the white light (CK) LED light source control group, and subjected to routine management and sampling measurement after flowering. The experimental results are as follows:
TABLE 1 Effect of different light treatments on tomato flowering and fruiting time
As can be seen from Table 1, the treatment by the LED light source formula provided by the invention leads the tomatoes to bloom 5-7 days in advance, leads the fruiting time to be 8-11 days in advance, and accelerates the production cycle of the tomatoes.
The influence of the LED light source formula treatment on the growth of tomato plants is as follows:
TABLE 2 Effect of LED light treatment on tomato plant growth
As can be seen from Table 2, the fresh weight and dry weight of tomato plants are increased compared with those of ordinary white light treatment by white-red-blue combined LED light source treatment, which indicates that the growth of tomatoes can be promoted by LED light source formula treatment.
The present example also determined the effect of LED light source formula treatment on the flowering sugar content of tomatoes, with the following specific results:
TABLE 3 influence of LED light treatment on the flowering sugar content of tomatoes
As can be seen from table 3, the treatment with the LED combined light source can increase the sugar content in the tomato flowers, and further increase the sugar content in the formed tomato fruits, thereby improving the tomato quality.
In conclusion, the cultivation method for promoting the tomatoes to bloom and fruit by using the LED light source improves the blooming quantity of the tomatoes, promotes the tomatoes to bloom and fruit in advance, accelerates the production period of the tomatoes, improves the quality of the tomatoes and has great economic significance.
