A brief analysis of the misunderstandings in the use of water-saving irrigation technology for flowers, and fertilization techniques and methods for edible fungi

Against the current trend of water resource scarcity, vigorously developing water-saving irrigation is imperative. Over the years, some advanced water-saving technologies have been promoted, such as sprinkler irrigation, micro-irrigation and drip irrigation. Whether in agriculture, forestry or the flower industry, their application has become increasingly widespread, but several misunderstandings still exist in their use.

First, flower enterprises do not have a full enough understanding of irrigation products. Although water-saving irrigation requires capital investment and personnel management both in the early stage and in later maintenance, once a water-saving irrigation system is put into use, its later benefits are very great. It is understood that a self-pressure drip-arrow drip irrigation system requires an investment of about 2000 yuan/mu, a micro-sprinkler irrigation system requires an investment of about 1000 yuan/mu, and a manual spot irrigation system requires an investment of only about 300 yuan/mu. Therefore, one should not look only at immediate interests but should take the long view. At the same time, because emitters have relatively high requirements for water quality, a filtration system must be used together with them during construction. If designed properly, its investment will not be very high, and timely maintenance in the later stage can also extend the service life of the filtration system, fully making up for the labor and water fee investment of non-water-saving irrigation methods.

Second, irrigation is not carried out reasonably in combination with the characteristics of the plants. Different crops have different irrigation needs for water and fertilizer, so one cannot simply pursue water saving.

For flowers with relatively high commodity value and a relatively long production cycle, such as poinsettia and Anthurium, their growth cycle is from May to October, or even longer, and during the growth period they must be watered at least once a day. If water-saving irrigation is adopted, it will not only save water and labor but also improve flower quality and uniformity and increase economic benefits.

For flowers with a relatively short production cycle and relatively low commodity value, such as Impatiens and cockscomb, their production management is relatively extensive, so there is no need to use drip-arrow micro-irrigation equipment; otherwise it is likely to result in high input and low output. In addition, frequent installation and removal of the drip-arrow parts can easily damage the equipment, affecting its normal operation and shortening its service life.

Of course, there are deficiencies in irrigation product services. On the one hand, the quality of domestic irrigation products needs to be improved, and there is a lack of independent brands; at the same time, product quality supervision systems should be strengthened so that products can meet relevant requirements before leaving the factory. On the other hand, customer service should be improved by teaching customers how to correctly use and maintain products and equipment. Construction enterprises should assess the situation, promptly feed back problems encountered during construction to manufacturers, and then manufacturers should update products according to actual needs, thereby meeting market requirements.
