The latest prevention and control methods of zucchini malformed melon

Zucchini is a very common melon vegetable in our daily life, which is basically cultivated all over our country. When growing zucchini, if you don't manage it well, there are many problems. And deformed melon is one of them, zucchini deformed melon will seriously affect the commodity value of zucchini. So how do you control zucchini malformed melons? The following small series will briefly introduce you, let's take a look together!

1. Causes of abnormal melons

There are many reasons for zucchini malformed melons, the first is caused by water and fertilizer problems. In the early stage of summer squash sitting melon, if the water and fertilizer are insufficient, it is easy to cause summer squash to appear pointed melon, and later it is easy to appear thin waist melon, but the water and fertilizer should not be too much, otherwise it is easy to form big belly melon. Moreover, if pollination is poor and pollen distribution is uneven, it will lead to depressions in the underpollinated parts. Then there is the temperature. Too high or too low temperature will affect the photosynthesis of zucchini, resulting in insufficient nutrition. Finally, female flower defects or bisexual flowers will cause progress.

II. Control methods

1. Fertilizer and water management

Zucchini's demand for fertilizer is still relatively large, and its ability to absorb fertilizer is also very strong. Although it has strong drought tolerance, it needs a lot of water during the fruit expansion period, so pay attention to keeping the soil moist. At the same time, sufficient base fertilizer should be applied, and appropriate amount of nitrogen and potassium fertilizer should be applied. Every time after picking melons, pay attention to topdressing once, base fertilizer is mainly farm manure, with appropriate amount of cake fertilizer, phosphorus fertilizer, etc. The moisture in the field should be controlled dry in the early stage and kept moist during the fruiting period.

2. Temperature regulation

When planting zucchini, if it is early-maturing cultivation, then it should generally be carried out by means of plastic film greenhouse cover shed. The suitable temperature for the growth of zucchini is generally around 20-30 degrees. The best temperature is about 20 degrees, and the soil temperature should be kept in the range of 18-23 degrees. Therefore, when we plant zucchini, we should adjust the temperature appropriately according to the change of weather. Reasonable uncovering of film, especially according to temperature changes and zucchini temperature requirements to regulate the temperature, promote nutrient accumulation, reduce abnormal melon phenomenon.

3. Artificial pollination

In addition to this, we have to do artificial pollination. Every morning at about 9 am, usually the peak period of male flower opening of zucchini, this time the male flower will be removed, and then take out the corolla. The anthers are scattered on the styles of female flowers, and generally a male flower can pollinate about three female flowers. It is best to be able to carry out when the air humidity is relatively high, which can improve the pollination effect. Pollinating should be uniform, in order to protect the fruit can also be treated with hormones. Apply 24d to pedicels or ovaries, but do not touch stems and leaves.

The above is a simple introduction to the control method of zucchini deformed melon. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
