And of the gardeners, the sunflower is a popular plant, known for its bright flowers and graceful forms. However, when you want to collect seeds to breed with expectations, the situation of unscathed seeds can be confusing and frustrating. This paper will explore in depth the common causes of the sunflower seeds and provide a set of practical solutions to help you address this problem。
Reason analysis
Inadequate light
Lighting is one of the key factors influencing the seed of sunflower. It takes plenty of sunlight to perform normal photosynthesis and reproductive growth. If the acacia is in an environment of insufficient light for long periods, it will not be able to accumulate enough energy to produce seeds。
Solution: ensure that sunlight is directly projected at least 6-8 hours per day. If natural light is not sufficient, the use of artificial light supplements may be considered。
2. Inadequate water and soil management
There are high requirements for soil moisture and drainage for acacia. Overwatering can lead to root decay, while the soil is too dry and hampers the maturity of seeds。
Solutions: rational watering based on the growth phase of the acetylene, keeping the soil wet but without water. A well-drained soil and suitable plant containers can be used to avoid excessive water retention。
3. Undernutrition or overnutrition
Fertilizer application needs to be appropriate. The lack of the necessary nutrients hinders the formation of buds and the development of seeds. On the contrary, excessive fertilizers, especially nitrogen, can lead to excessive growth of the sunflower leaf and neglect of reproductive growth。
Solutions: rational application of fertilizers and timely supplementation of full nutritional fertilizers, as required by plant growth. It is recommended that the application of balanced compound fertilizer be applied every fortnight in the long term, and that the application of nitrogen fertilizer be reduced or discontinued during the flowering period。
4. Inappropriate trim
Cutting is necessary during the growth of the acacia, but inappropriate shears remove growing bouquets or buds, thereby affecting the formation of seeds。
Solutions: avoid overcuting during plant growing seasons. Shears should be carefully trimmed with only the aging leaves and the weak parts to ensure the integrity of the sequence。
5. High or low temperatures
Temperatures are equally important for the flowering and seeding of sunflowers. Extreme temperature conditions, whether too high or too low, may affect pollen activity and seed formation。
Solutions: to understand and maintain temperature ranges suitable for the growth of sunflower, typically from 15°c to 25°c. During the summer, high temperatures are avoided and winters are kept warm and cold。
Practical techniques
Regular pellets: each year pellets can update the soil and increase its permeability and fertility。
(b) polluting in due course: artificially assisted pollination can be attempted if the acacia is in poor condition in the natural environment。
Selecting the right species: some of the sunflower varieties are harder to find, and choosing the easy-to-finish varieties can increase success rates。
Concluding remarks
As a result of the above analysis, it can be found that unscathed seeds are usually directly associated with the conditions of growth, such as light, moisture, soil, nutrition and temperature. With appropriate management measures and solutions to these problems, you will have the potential to successfully induce your sunflower to grow full seeds. It is hoped that these methods and techniques will help you to better develop the sunflower and appreciate its beautiful flowers and seeds。
