Description
Technical Field
The invention relates to the technical field of cucumber seedling culture, in particular to a method for supplementing light for cucumber seedling culture by using an LED lamp in a sunlight greenhouse in winter under low light.
Background
The growth and development of plants are realized by storing organic matters through synthetic action, so that the illumination plays a very important role in the growth and development of plants. The seedling culture of the vegetables is an important link in vegetable cultivation, and if the photosynthesis of seedlings is insufficient in continuous rainy days, the synthesis of organic matters of plants is blocked, and the normal development of the seedlings is seriously inhibited. The robust development degree of the seedlings directly influences the growth and development of the plants, further influences the blossoming and fruiting of the plants, and further influences the growth vigor and economic benefit of the current season vegetable planting.
Among them, cucumber is a worldwide vegetable that is generally cultivated, and has a large planting amount and also plays an important role in market supply. At present, melon vegetables are mainly cultivated in a seedling transplanting mode in China, excessive growth of melon vegetable seedlings is one of the most common problems in the seedling raising process, and the melon vegetables are more difficult to control compared with other vegetable varieties (such as solanaceous vegetables). If the environmental control in the seedling raising process is improper, the seedlings are extremely easy to overgrow, so that the quality of the seedlings is reduced, the growth, the flower bud differentiation, the fruit setting and the fruit development are further influenced, and the yield and the quality of the cucumbers are finally influenced. Intensive seedling culture can more effectively improve production efficiency and product quality, but the low-temperature short irradiation phenomenon is easily caused under the current facility conditions, and the low-temperature short irradiation is one of the reasons for the spindly growth of seedlings (the high temperature at night can also cause the spindly growth of seedlings). However, effective control of excessive growth of seedlings is a key link for cultivating high-quality strong seedlings, chemical substances such as plant growth regulators and the like are often used for regulating the growth of the seedlings in production practice, the method is easy to cause vegetable pollution and influence human health, and the cultivation of the high-quality seedlings by utilizing the light regulation and control technology is a novel technology which is environment-friendly, effective, simple and easy to implement, and has outstanding advantages.
Research shows that the artificial light source regulation and control technology is one of effective ways for culturing strong seedlings, and the LED light source is a cold light source, so that the LED light source has the advantages of long service life, pure spectrum, low energy consumption and the like compared with the traditional light source. The different LED light qualities have obvious influence on the growth of the cucumber seedlings and have differences, so the invention researches and tests which light is more beneficial to the growth of the cucumber seedlings and the cultivation of strong seedlings.
