What fertilizer to use during the color change period of Xiahei grapes
An introduction to the maintenance of fruit trees, particularly Xiahei grapes, discussing what fertilizer to use during the color change period. Let's take a look with the editor!
Xiahei grapes are gradually entering the coloring maturity period. It is a known difficulty to get Xiahei grapes to color properly. Many fruit farmers are unaware of what fertilizer to use during the color change period. Below is a practical coloring plan provided by a teacher.
① In vineyards with bags, the entire garden should be sprayed with Bordeaux mixture (the most affordable and effective disease control solution. We will focus on analyzing this in detail on Kuaishou [Z-B] later), if diseases occur, a clear Bordeaux mixture (neutral) + 80% dimethomorph or other downy mildew treatment fungicides can be chosen.
② Management of water and fertilizer under the trees and during the coloring period
EM original solution can be used at 2-3 bottles per mu, mixed with brown sugar and chitin to promote root growth, plus potassium dihydrogen phosphate 5-10 kg (adjust according to yield, can be applied together with全能钾王5-10 kg for full nutrition), and repeat the same amount after ten days until the grapes mature. A special note: only with roots can absorption occur, and with enhanced absorption capacity, a small amount of fertilizer can lead to healthy plant growth. The conventional chemical fertilizer dosage can be reduced or halved.
③ When grapes enter the coloring period, spray the leaves with EM original solution 300 times + brown sugar 300 times + potassium dihydrogen phosphate 500 times + rare earth trace fertilizer 300 jin of water, or spray 3C leaf fertilizer 500 jin + EM original solution 500 times to promote natural sugar and coloring.
④ If coloring is difficult or yield is too high, 3C leaf fertilizer 300 jin of water + Beauty in Red Powder 150 jin of water (once at the beginning of coloring), second application with Beauty in Red Powder 120 jin of water, third application with 90 jin of water. In special cases, Beauty in Red Powder 60 jin of water can be used to promote coloring.
⑤ After early-maturing grapes are harvested, promptly supplement with月子肥, leaf spray 3C leaf fertilizer, and apply calcium nitrate 40 jin underground to supplement月子肥.
⑥ Prepare in advance, apply fermented base fertilizer in autumn (extremely important).
