What to Do When Grape Inflorescences Are Small
Sharing the introduction of green plants and flowers on what to do when grape inflorescences are small. The following is a detailed introduction for you.
What to Do When Grape Inflorescences Are Small
The quality and quantity of grape inflorescences directly affect the yield and quality of grapes later on. Many orchards generally have fewer inflorescences, small inflorescences, especially in the early cultivation of fruit trees, and even no inflorescences. What are the reasons? How to solve and remedy? Let's take a look with the editor.
Reasons for Small Inflorescences
1. Lighting Reasons
Lighting has a significant impact on the differentiation of grape flower buds. Light can be divided into long-day and short-day. If the density of grape branches is too high, insufficient lighting can lead to a decrease or absence of inflorescences the following year.
2. Nutrient Reasons
Grapes overlap in the periods of flower bud differentiation, new growth, flowering and fruit setting, and fruit expansion, and these periods require a large consumption of nutrients. If the growth of new shoots and the development of fruits dominate in the nutrient competition, while the differentiation of flower buds and inflorescences are at a disadvantage, it will lead to malnutrition in winter ducks, affecting flower bud differentiation, thus resulting in few inflorescences.
3. Orchard Management
Not applying or applying insufficient base fertilizer, excessive fruit load on trees, excessive application of nitrogen fertilizer, neglect of organic fertilizer, and poor control of pests and diseases can lead to insufficient nutrient reserves in trees, consume a large amount of nutrients, difficult root absorption (S-Y) fractionation, causing the withering and degeneration of tree inflorescences, or even the absence of inflorescences and excessive new shoots in the second year.
4. Early Sprouting
In greenhouse cultivation, if the greenhouse is sealed and heated in advance, it can lead to insufficient cooling during the flower bud differentiation process, affecting flower bud differentiation, or prematurely wiping flower buds to break dormancy, causing frost damage and new position damage during the flower bud to inflorescence period.
Remedial Measures
For fruit trees with few buds and inflorescences, 5 kilograms of balanced water-soluble fertilizer should be supplemented at the root, combined with biostimulants. By enhancing the absorption capacity of the roots, and applying foliar spray fertilizers, the trees can quickly replenish nutrients and improve vitality as soon as possible. When new shoots have more than 10 leaves, measures such as pinching the tips can be taken to inhibit the nutritional growth of fruit trees, and retain the two summer buds below the heart to delay the germination of winter buds and promote inflorescence differentiation. For spring shoots without inflorescences, they can be laid down early, and the application of organic fertilizer and trace elements should be increased appropriately to promote the maturation of spring shoots until the secondary shoots germinate, and use the secondary shoots to form inflorescences for the cultivation of the second batch of flowers and fruits.
