Cultivation techniques of fresh cut flowers of oriental lily

When it comes to the production of fresh cut flowers of oriental lilies, it is both easy and difficult for growers. The easy thing is that no matter who is planting oriental lily cut flowers for the first time, there will be a harvest, and cut flowers will be harvested, while the difficult thing is that it is really difficult to cultivate high-quality cut oriental lily flowers. This is the most touching for many growers who have just started the production of fresh cut lilies. In fact, as long as the grower has mastered several cultivation techniques, the production of fresh cut lilies is not difficult. Here are a few essentials for your reference.

The key point is that a line should grow better.

The quality of fresh cut flowers of oriental lily is good or bad, in addition to the factors of planting bulb itself, it mainly depends on the development and growth of root and stem root of lily in the process of growth. In other words, if the root system of the lily is developed, the plant will grow vigorously. In order to produce high-quality fresh cut lily flowers, the main thing is to make the root system of the bulb develop well. As long as the root system and stem root of the bulb grow well, the quality problem of fresh cut flowers will be solved. Although this truth is well known, many growers ignore it in the planting process. In short, it is critical to make the roots of bulbs develop and grow well.

Essentials 2. Soil improvement

The quality of soil plays a decisive role in cut flower production. As each plant has different requirements for soil, soil improvement has become a top priority, and the soil must be improved to meet the special external conditions needed for plant growth. In other words, the soil should be improved into external conditions suitable for the root growth of lily bulbs. As we all know, the effects of soil physical and chemical properties on plants are very important. Improving soil into a water-vapor balance state with strong water and fertilizer conservation, water supply and fertilizer supply capacity can promote plant root respiration and rapid growth. Good soil, strong microbial activity, soil organic matter can be converted into available substances for plant root absorption, but also increased root activity. The developed root system can enhance the ability of plants to absorb inorganic phosphorus.

Generally speaking, developed roots can absorb more nutrients from the soil and further promote root growth. What kind of soil is needed for the root growth of lily bulbs?

In principle, the soil is required to be loose and well ventilated. There is plenty of air in the soil (be careful not to be too breathable, because the air and water in the soil exist in the soil void at the same time, so keeping the water vapor balance is the best). To do this, soil improvement is needed because it is difficult for the existing soil to meet this requirement. Although lilies can grow in any soil structure, the soil structure is more stringent if the roots of lilies are to grow well.

The more successful improvement methods are as follows: 2 parts of loam to 1 part of peat soil, or 3 parts of loam to 1 part of peat soil, 2 parts of loam to 1 part of peat soil plus 2 parts of rice husk, or 3 parts of loam to 1 part of peat soil and 2 parts of peat soil plus 1 part of peat hull. The depth of soil improvement should be about 20 cm. This kind of soil structure can be treated with general soil disinfectants and fungicides. When continuous cropping, if conditions permit, it is better to plant twice, invert stubble once, or carry out physical disinfection. However, it is not enough for the physical conditions of soil to meet the requirements of lily root growth, and the soil chemical conditions need to be adjusted.

It is generally believed that the ph of normal root growth of lily is 5.5 to 6.5, but this is not accurate enough. The ph value that is really suitable for lily root growth is 5.5, which can be controlled at this point. Oriental lily grows best and root growth is the most developed. Of course, lilies will also grow when the ph is slightly higher or higher, but precisely, the higher the ph, the worse the lily's growth, because it grows in an environment that is not conducive to root growth. For example, in Lingyuan and Kazuo in western Liaoning, China, the ph value of the soil is as high as 7.6, while the ph value of water is also high, and the ph value of water in some areas is as high as 8.0 (due to Rain Water in summer, the ph value is slightly lower). Seed China reminds you that soil improvement must be carried out. In the process of soil improvement, when adding materials that can reduce ph, acidic fertilizers can be used when fertilizing, or acidic materials can be added when watering. After such improvement, growers can get better quality of cut flowers.

The specific method of adjusting ph value: acid soil mixed with a certain amount of lime material can increase ph value; alkaline soil mixed with a certain amount of sulfur powder or gypsum can reduce ph value. The effect of sulfur powder is better than that of gypsum, because a certain amount of sulfur powder can promote plant rooting. If the ph of the water is too high, you can mix a certain amount of sulfuric acid and nitric acid solution, and adjust the ph of the water to about 5.0.

Three essentials: rational fertilization

Compared with other flowers and plants, lily needs little fertilizer, but lily is a fertilizer-loving plant. In the process of soil improvement, adding more rotten barnyard manure is of great use to the growth of lily. Barnyard manure contains a lot of organic matter and microorganisms. Decomposition in soil can not only supply lily with a large number of elements, but also supply trace elements, but also promote the decomposition of organic matter in soil and produce a large amount of carbon dioxide for lily carbon assimilation. Barnyard manure can supply not only inorganic nutrients of lily, but also soluble organic compounds. Because barnyard manure can promote the activity of microorganisms, thus produce biological substances, promote the development of lily roots, and make the roots absorb nutrients better.

Generally speaking, barnyard manure plays a very important role in improving soil fertility. It can not only improve soil physical and chemical activity, but also coordinate water, fertilizer and air in soil, and better meet the needs of lily root growth. Seed China reminds you: according to the actual cultivation effect, it is best to apply two cubic meters of barnyard manure for every 100 square meters of soil, which can be carried out at the same time when improving the soil.
