Seven key points
1. Large ridge cultivating loose soil
Large ridge cultivating loose soil can improve soil fertility and soil permeability, promote rooting of vegetable plants, reduce root rot, and reduce surface salt damage caused by long-term fertilizer application.
Second, planting roots and soil
Solanum vegetables often die from diseases such as rhizome rot, blight, verticillium wilt, and bacterial wilt, and the root-salt soil can be degraded by planting roots under the plant to inhibit disease and prolong the fruiting period.
Third, remove the old leaf disease leaves
Solanum, melons, beans, etc., by removing old leaves and diseased leaves, can make full use of nutrients and nutrients to reduce pests and diseases.
Fourth, diligent plant nutrient
Replenishing plant nutrients can increase photosynthetic production and increase yield.
V. Regular prevention and control of epidemics
Due to the high temperature and rain in May, Phytophthora bacteria are occurring rapidly, so it is necessary to strengthen the prevention of epidemics.
6. Adding bio-organic fertilizer
Add bio-organic fertilizers, such as biological fertilizers (such as phosphate-dissolving bacteria, potassium-dissolving bacteria, actinomycetes, etc.) to improve fertilizer utilization and improve fruit quality.
Seven, ventilation and moisture insulation
According to the weather, crops, growth conditions, etc., take early air outlets, open air outlets, and half an hour in the middle of the night to do the ventilation and cooling measures.
Three don't
First, do not water at noon
Watering at noon will cause the roots of the vegetables to “fried†the roots after being stimulated by cold water, reducing the yield. The optimal watering time is before 10:00 in the morning.
Second, do not flood the water
Large water flooding will cause water accumulation, root respiration is inhibited and prone to rotten roots, which seriously affects vegetable yield, so it is best to alternate watering.
Third, don't let dry and wet
Do not suddenly dry and wet, it is easy to make the speed of fruit enlargement and cracking phenomenon, especially in tomato and melon crops.
Three bogey
First, avoid excessive water control
Long-term control without watering will cause the plants to wilting due to lack of water. It is easy to affect the absorption of medium and trace elements by soil drought, which causes the occurrence of viral diseases. Therefore, it is best to take small measures. The watering method of watering is to determine the time and frequency of watering according to the dry and wet conditions of the soil in the shed and the weather conditions.
Second, avoid excessive leaf thinning
The leaf smears should be moderate, follow the principle that the upper leaves of the fruit are “more than not crowded†and the leaves of the lower part of the fruit are “less and fineâ€. Excessive smearing of the leaves will cause the sun to burn directly to the fruit and reduce the quality of the fruit.
Third, avoid the top air outlet without insect net
There is no insect net in the top air outlet, which will cause crops to be invaded by pests, such as aphids and thrips, which will reduce the yield and quality of vegetables.
