With the improvement of people's living standards, the flower breeding industry has also developed rapidly, but it is not so simple to raise flowers well. Basic flower cultivation techniques such as soil treatment, sowing and transplanting are all skills that flower farmers must master. The following small series will tell you about flower planting techniques.
(A) to master the soil treatment technology
One of the conditions for healthy growth of flowers is the ground. Thick soil, smooth drainage, suitable environmental conditions and certain nutrients can ensure the normal growth of flowers. Most flowers growing in the open field require the PH value of the soil to be 7.0, that is, the soil is neutral, while flowers in the greenhouse need acidic soil.
There are three major elements in the nutrients needed by flowers: nitrogen, phosphorus and potassium; There are three medium elements: calcium, magnesium and sulfur; Trace elements include iron, beryllium, copper, zinc, manganese and chlorine.
(2) Master the technical details of sowing.
Sowing is the initial stage of flower cultivation and planting, and it is also the key point of healthy growth of flowers, which must be highly valued. As far as the sowing stage is concerned, it is necessary to do a good job in three aspects: arable land, soil preparation and soil preparation.
Cultivated land: divided into spring ploughing and autumn ploughing, the depth of cultivated land should be set at 20 ~ 40 cm, not too deep.
Soil preparation: keep the permeability and emptying of soil by crushing, turning over the soil and sorting out sundries, and master the water content of soil in this process to create soil moisture suitable for flower planting.
Sowing: affecting the techniques of flower cultivation and the later growth of flowers. Therefore, we should pay attention to the time and method of planting flowers.
(3) Do a good job of thinning and transplanting.
Spacing: After sowing, if the seedlings are too dense, planting spacing is needed to ensure the good growth of flower seedlings. It should be noted that the interval between seedlings should not be too late, otherwise it will lead to excessive growth.
Transplanting: it is divided into two steps: seedling raising and planting.
Seedling raising: hanging the flower seedlings out of the seedbed.
Planting: it is divided into permanent planting and follow-up planting. Fixed planting: seedlings are not transplanted after planting; Stay close: after the seedlings grow to a certain period of time, they need to be replanted.
(D) Strengthen fertilization management
Rational fertilization and proper watering are the necessary conditions for the healthy growth of flowers. Fertilization includes base fertilizer and topdressing. Basic fertilizer is generally applied in the early stage of flower planting and is the basic fertilizer for flower growth; Fertilization in the process of flower growth is called topdressing, in order to ensure that the flower growth has sufficient nutrition.
(5) weeding diligently
Weeds will compete with flowers for nutrients, hinder their healthy growth, and are also breeding bases for germs and pests. Therefore, attention should be paid to weeding in the process of flower growth to create a suitable growth environment for flowers.
(6) Prune branches
Cutting off diseased branches, dead branches and residual branches is also an important part. This can avoid the secondary infection of flowers and reduce the number of germs and pests to some extent.
(7) Prevention of pests and diseases
In order to prevent flowers from being harmed by pests, we should choose some suitable drugs to be used timely, accurately, safely and reasonably, and at the same time strengthen field management and strengthen the prevention and control of various pests and diseases.
The above are the flower cultivation techniques arranged by Bian Xiao. It can be seen that raising flowers is not as simple as watering. Only by mastering the necessary flower cultivation techniques can flower cultivation become better and better.
