Effect of high temperature weather on passion fruit

Passion fruit is a very common fruit in our life, and its planting area is also very large in our country. The nutritional value of passion fruit is also very high, so now more and more people plant it. When planting passion fruit, we should pay attention to the weather change. Especially the high temperature weather will have a great impact on the growth of passion fruit. So what effect will the hot weather have on passion fruit? Let's have a look together.

1. The influence of high temperature weather

Passion fruit buds normally bloom around 11:00 in the morning after they mature. At the time of flowering, if it is high temperature, it will affect the pollination and fruit setting of passion fruit. On the day of flowering, if the temperature is higher, the pollination fruit setting rate will be lower. The flower bud period of passion fruit is generally about three weeks, and the suitable temperature for flowering growth is about 22 degrees. When the temperature is higher than 30 degrees, then it will affect the physiological metabolism of passion fruit. Lead to deformity of flower organ development of passion fruit. It will also cause the pollen tube to shrink, and the pollen tube elongation of male pollen will be affected, resulting in a decrease in the rate of pollination and fertilization.

2. How to improve the fruit setting rate in high temperature weather

When planting passion fruit in hot weather, pay attention to building flat-roofed scaffolding. After building the flat-roofed scaffolding, the coverage rate of branches and leaves in the field can reach about 80%. Can prevent most of the soil from being exposed to direct sunlight. Restrain the heating rate in the field, so as to achieve the purpose of increasing the fruit setting rate. And we can also grow grass between the rows of passion fruit plants, which can also reduce the temperature in the field. Inhibiting water evaporation can also achieve the purpose of supplying water. Prevent passion fruit from affecting the lack of moisture and leading to the decrease of fruit setting rate.

Then pay attention to the application of adequate fertilizer, fertilizer is a main way to obtain growth nutrition of passion fruit. When we are topdressing, we should pay attention to the proportion of nutrients in fertilizer to ensure the diversification of fertilizer and provide adequate growth nutrition for passion fruit. Because in the passion fruit flowering period, if the temperature is higher than 30 degrees, then the passion fruit pollination and fertilization is very disadvantageous. Therefore, in the flowering period, if the temperature is too high, then we should spray water in time to cool down, and artificial pollination can be carried out during flowering to improve the fruit setting rate.

3. Artificial pollination

Artificial pollination is a key measure to increase the fruit setting rate of passion fruit in high temperature weather. Because passion fruit pollen will gradually lose its vitality in high temperature weather, the rate of self-pollination will decrease, so artificial pollination is essential. However, we can spray an appropriate amount of bee lure in the weather to lure bees and use bees to pollinate. It can increase the fruit setting rate by about 30%, and spraying bee attractant can also increase the added humidity and the stickiness of the female style. Avoid pollen tube atrophy, so as to achieve the rate of pollination and fertilization.

The above is a brief introduction to the effect of high temperature on passion fruit. That's all for today's introduction. This article is for reference only. I hope it can help you all.
