Proper coloring measures for zucchini seeds can form a protective layer with certain functions and coating strength on the outside, promote growth, and have certain excellence in appearance after maturity. Therefore, how to take effective measures to help its coloring become even has become the most concerned issue for many vegetable farmers.
The light should be sufficient. Timely remove dust and pollutants on the greenhouse film to ensure sufficient lighting conditions to promote fruit coloring. After planting the grass thatch, try to uncover the grass thatch as early as possible and cover it late to increase the light time of the zucchini seeds. If necessary, timely Measures such as thinning out excess branches, old leaves, diseased leaves and hanging reflective curtains on the back wall can increase the lighting time of the fruits in the shed and promote fruit coloring.
The temperature is well controlled. Temperatures that are too high or too low during the coloring period of zucchini seeds will affect the formation of pigments. So give it the proper planting temperature.
The supply of water and fertilizer must be balanced. Unreasonable fertilizer application will seriously affect the coloring of zucchini seeds. For example, too much nitrogen will cause the plant to grow too strongly. If there is insufficient water at this time, green shoulder fruits will occur. Nitrogen deficiency will cause the fruit shoulders to turn yellow. Potassium deficiency will cause the fruit shoulders to grow. It appears yellow-green. When the vascular bundles in the heart of the fruit are lignified and lack boron, the fruit shoulders remain green and have necrotic spots. Preventive and control measures include timely supplementation of nitrogen, phosphorus and potassium fertilizers. One kilogram of borax per mu is used to supplement boron fertilizer. At this stage, under sunny weather, watering should be done every other day or so depending on the soil moisture.
In addition, every ear of zucchini seeds needs to be top-dressed in time when it enters the expansion stage. It can be applied with fully nutritious and fully water-soluble fertilizer, and the nutrients per kilogram per mu can be fully replenished to avoid poor coloring of the fruits due to unbalanced nutrient supply. .
