How can we achieve reasonable fertilization of loofah?
Combining the cultivation techniques of loofah today, the rational fertilization techniques of loofah are summarized as follows:
　　 1. In the seedling stage of loofah, in order to ensure the normal differentiation of flower buds, the number of flower bud differentiation and the growth of vegetative bodies, appropriate application of nitrogen fertilizer should be applied at the same time as appropriate application of phosphate fertilizer and potassium fertilizer. Related studies have shown that at high nitrogen levels, the addition of phosphate fertilizer can promote early flowering results. Therefore, fertilizers with high nitrogen and sufficient phosphorus should be applied during the nursery period. For example , 20-9-11 sulfur-containing compound fertilizer and other similar high-nitrogen compound fertilizers are more suitable for the selection of loofah seedlings. When fertilizing, it is necessary to apply organic fertilizer according to the local soil fertility level to ensure that the loofah grows healthily during the nursery period.
　　 2 , in the growing stage of loofah, this period is the period of loofah vegetative growth and reproductive growth, but also to ensure the key to high yield of loofah. During this period, loofah growth requires a large amount of nitrogen nutrition and potassium nutrition, but care should be taken not to apply excessive nitrogen fertilizer. If the nitrogen fertilizer is applied too much, the plant will grow long and delay the flowering result. Therefore, in this period, the base fertilizer should be the main method, and the fertilization method should be supplemented by the divided top dressing. The base fertilizer is mainly organic fertilizer, combined with the application of high nitrogen and potassium compound fertilizer, for example: 17-7-17 sulfur compound fertilizer and the like. More suitable for loofah in the growing season. Topdressing is generally applied with water after the harvest of the previous loofah, and the topdressing must be done a small number of times in order to facilitate the full absorption of the loofah. If the controlled release BB fertilizer (the true extended release product of controlled release fertilizer, not the stable dosage form of Entek), the number of fertilization of loofah will be significantly reduced, and the economic benefit of loofah cultivation will be improved.
In addition, according to the growth of loofah, it is necessary to properly apply micro-fertilizer to ensure its healthy growth.
All in all, loofah as a kind of melon and fruit vegetables requires a relatively large amount of fertilizer. The above summarizes the current relevant research results for the reference of farmers' friends. The specific fertilization amount should be determined according to the local soil fertility level. However, it is necessary to be specially reminded that after fertilization, it must be irrigated, and it must be combined with fertilizer and water. In the current era of labor- intensive labor, it is recommended to use controlled-release BB fertilizer (an extended product of controlled release fertilizer, not a stable dosage form such as Entek), so as to significantly reduce the number of fertilization, greatly reduce fertilizer labor, reduce production costs, and improve loofah. Economic benefits of planting
The IP rating of Led Vapor Tight Fixtures is 66. It is dustproof, waterproof, anti-corrosion, and anti-UV. It can effectively prevent the lamp body from being easily oxidized and broken after exposure. The integrated design makes installation more convenient and quicker. It does not need to be installed and connected in series after the lamp body is open like the traditional three-proof light. So it can effectively shorten the construction period and reduce labor costs.
There is a respirator at one end of the lamp body, which can avoid thermal expansion and contraction when the lamp body is working, and water droplets appear on the wall of the lamp body, which affects the service life of the lamp beads.
Our LED Tri-proof Light are connected in series without the use of tools. Cylindrical design, which make cleaning more easily.
