How to plant watermelons to achieve high yields
The editor brings you the introduction of how to plant watermelons to achieve high yields and the green plant flower related introduction of watermelon planting management techniques. The following is a detailed answer for you by the editor.
Watermelons, with a variety of varieties and a wide cultivation range, are indispensable fruits for people in the summer.
Once summer arrives, the competition among watermelon farmers is fierce, and good watermelons are in short supply. However, why do some people grow high-quality and high-yield watermelons, while others experience blossom and fruit drop during the planting process, resulting in low yield and poor quality?
Actually, in addition to the advantages of the variety itself, daily management also involves many techniques. Today, Xishi duo shares several methods to improve the quality and increase the yield of watermelons.
Selecting suitable soil
When cultivating watermelons, choose a plot with loose soil, deep soil layer, fertile soil, good drainage, sufficient sunlight, and a location that gets afternoon sun. It is not advisable to plant watermelons continuously in the same field; generally, a 4-5 year crop rotation is recommended. Otherwise, the wilt disease can be severe. The best previous crops are rice, corn, and other grass crops, followed by vegetables like potatoes and cabbage. However, if the previous crop is a melon vegetable, planting watermelons can lead to severe diseases and should not be chosen.
The watermelon field must be deeply cultivated, preferably in winter.
In fields that have been deeply cultivated or have a deep cultivation base, dig drainage ditches around the perimeter, open ridges with a spacing of 2.4-3.0 meters (ditch width 0.5 meters), apply base fertilizer in a trench on one side of the ridge, and apply 2500-3000 kilograms of farmyard manure per mu, plus 15-20 kilograms of phosphate fertilizer, 20-25 kilograms of 45% compound fertilizer, 2 kilograms of borax, and 1 kilogram of zinc fertilizer.
A small amount of crystal敌百虫 can be mixed into the base fertilizer to prevent underground pests. Cover the base fertilizer trench and shape it into a watermelon ridge, then cover with plastic film and wait for sowing or transplanting.
Reasonable irrigation
Watermelons in the fruit expansion stage require sufficient water for growth, but irrigation must be moderate and uniform. Generally, water every 5-7 days to keep the soil slightly dry and moist. If the soil dries out and then becomes wet, it is easy to cause fruit cracking, so it is important to water frequently with small amounts to maintain even moisture. Please note that if using drip or spray irrigation, water according to the actual conditions in the greenhouse.
Proper ventilation
During the fruit expansion stage, it is important to master the ventilation time. Generally, start ventilating when the greenhouse temperature is higher than 28°C and stop when it is lower than 26°C. This can be judged based on the growth of the watermelons in the greenhouse and the outside weather conditions. If the watermelons are growing vigorously, extend the ventilation time to control growth, and if they are weak, shorten the ventilation time to promote growth.
When the outside temperature is high and sunlight is strong, extend the ventilation time to avoid excessive greenhouse temperature. When the temperature is low or it is rainy outside, shorten the ventilation time, or use the method of short and frequent ventilation to avoid excessive humidity and low temperature inside the greenhouse.
Preventing diseases
The main diseases that harm watermelons during the fruit expansion stage are wilt disease, vine wilt disease, and anthracnose. These are three common diseases in watermelon cultivation, and I hope all planting friends can pay attention to them, discover and control them in a timely manner.
The comprehensive knowledge explanation of how to plant watermelons to achieve high yields and watermelon planting management techniques shared in this article, I hope it helps you.
