Common Misconceptions about Applying Base Fertilizer to Grapes in Autumn
The best period for fertilizing grapes is usually after harvesting the fruit and before the leaves fall in autumn. Applying base fertilizer during this period is beneficial for the recovery of the fruit trees and the improvement of the quality and quantity of flower buds. Below is a brief introduction to the misconceptions about applying base fertilizer in autumn.
Ignoring the Use of Organic Fertilizers
Organic fertilizers play an irreplaceable role in the application of autumn base fertilizer for grapes, as they contain a rich and comprehensive range of nutrients that can improve the soil and promote the activity of soil microorganisms. Additionally, organic fertilizers produce a large amount of organic acids during decomposition, converting insoluble nutrients into soluble ones, thereby increasing the utilization rate of soil nutrients.
Organic Fertilizers Not Decomposing
During the production of organic fertilizers, materials such as chicken manure, sheep manure, cow dung, and pig manure are used. While their properties may differ, they all have the same requirement—thoroughly decomposed. The drawbacks of applying undecomposed organic fertilizers include: not providing nutrients to grapevines in a timely manner, producing harmful substances that can damage the vine roots during the decomposition process in the soil, and the high heat generated by certain manures like sheep dung during decomposition, which can cause root burn. The timing of the effectiveness of decomposed organic fertilizers does not match the nutrient needs of grapes, leading to a loss of fertilizer efficiency.
Improper Timing for Using Organic Fertilizers
The primary function of organic fertilizers is to restore the vitality of trees, so they should be applied after grape harvesting (late September to mid-October) — not too early or too late. If applied too early, the aerial parts of the grapevines are still growing. Deep digging during the application of base fertilizer can cause damage to the roots and excessive transpiration of leaves, leading to leaf drying.
Applying base fertilizer in winter, after the leaves have fallen, when the soil temperature drops, root activity ceases, and leaf function stops, greatly reduces fertilizer utilization and the slow release of fertilizer efficacy can affect fruit flowering. Applying base fertilizer in spring cannot meet the energy needs of grape sprouting in spring, but it starts to take effect in summer, easily causing excessive grape growth, unstable fruit setting, and uneven berry size.
Base Fertilizer Application
Selecting the right base fertilizer is key, but the appropriate application method is also essential. Common incorrect methods include shallow digging, moving soil, direct spreading, and rotary tillage, which are contrary to the application of base fertilizer and the growth of grape roots in autumn. Improper depth control and shallow application (most common in production) can lead to fertilizer waste,不利于根系 absorption, and reduced fertilizer utilization. If the fertilization location is too concentrated, it often results in fertilizer loss.
Inadequate Fertilizer and Water Management
Matching fertilizer with water is a prerequisite for improving fertilizer utilization. In the production process, many people focus on fertilization while neglecting water management. Although a large amount of fertilizer is applied, the efficiency of fertilization cannot be maximized due to soil drought, which will greatly affect the grape yield next year.
Complementary Use of Base Fertilizer
Based on the first point, using base fertilizer is very beneficial, but it needs to be properly matched to fully realize its effects. This includes paying attention to the use of organic fertilizers (farmyard manure or commercial organic fertilizers), using trace elements such as calcium, magnesium, boron, and zinc, applying bio-fertilizers to effectively regulate beneficial bacteria in the soil and promote root absorption, and adjusting the soil pH while using base fertilizer. Currently, most common grapeyards are acidic.
The above is about the use of base fertilizer. When applying base fertilizer to grapes in autumn, it is essential to recognize these six misconceptions and avoid incorrect application. We must control the use of base fertilizer properly.
