How to improve the market quality of grapes? Detailed practical measures
1. Cluster selection: keep good clusters with a neat shape, uniform fruit set, and a drooping posture. 2. Cluster shape adjustment: on the basis of conforming to the variety's natural shape, tidy them up slightly; clusters of the same variety throughout the vineyard should be basically uniform. 3. Cluster elongation: for varieties with a high fruit-set rate, when the cluster is 7-10 cm long,...

Detailed Explanation of Practical Experience in Off-Season High-Yield Cultivation Techniques for Pineapple
Pineapple planting methods include double-row, three-row and four-row. In the double-row system, the commonly used bed and furrow together are 150cm wide, with a single plant arranged in each of the two rows. Its advantages are: the bed furrow is relatively wide so the fibrous roots can spread outward, the plant and row spacing on the bed is relatively uniform, the stem bases press against each other, and the leaves spread out to form a hemispherical surface, which can fully utilize sunlight and easily form between-row...

How to prevent spring wheat from freezing damage? Practical anti-freezing methods
"Lodging" is one of the main obstacles affecting wheat yield under high-fertilizer and high-water conditions. In recent years, the promotion and application of plant growth regulators in wheat production has opened up a new way to prevent lodging and promote yield increases, and is an important supporting technical measure for high and stable wheat yields. 1. Spraying paclobutrazol: during the wheat stem elongation stage, every...
