Matters needing attention in planting zucchini in greenhouse in early spring

Zucchini is a very common fruit and vegetable in our daily life. It is distributed in all parts of our country, and its market demand is also very large. As a result, zucchini are now being planted in greenhouse for out-of-season cultivation, and when greenhouse zucchini is planted when the temperature is low in early spring. There are many places that need us to pay more attention to, but what are the specific ones? Let's take a look at the matters needing attention in the cultivation of zucchini in the greenhouse in early spring with the editor.

1. Hanging vines and falling vines

When zucchini is planted in the greenhouse, the planting density of zucchini is higher, and the growth cycle is longer. Therefore, in order to ensure that the plant can receive light evenly, it is convenient for pollination, medicine and so on. We should pay attention to the work of hanging vines in early spring so that the stem vines of zucchini can grow upright. When hanging the vine, you can first pull an iron color on each row, and then use a rope to connect each melon seedling with the wire. The upper end of the rope is tied to the wire and the lower end is connected to the base of the stem. As the zucchini branches grow, the rope and the branches will be intertwined.

2. Reasonable flower thinning

In order to ensure a balanced growth relationship between seedlings and fruits, we should also pay attention to flower thinning. Remove some female flowers, retain enough pollinated male flowers, and erase superfluous ones. And if necessary, we should also do a good job in fruit thinning to avoid excessive nutrient consumption. Female flower thinning should be carried out when it is just exposed, and the number of thinning should be controlled according to the growth of the plant. If the growth is weak, then you can first remove the root melon, and then keep a female flower in the third section. And if the growth is strong, you can keep the root melon, but you should pay attention to timely harvest and keep a female flower in two sections. Then control the amount of melons according to the growth of the vines.

3. Anti-sprouting update

Now the cultivation of zucchini is mainly based on grafted seedlings, and zucchini is very easy to sprout after grafting. So at this time we should remove the sprouting tillers in time to avoid sprouting and growing up to seize the nutrition of zucchini and affect its normal development. When cultivated in the greenhouse, the growth cycle of zucchini is longer, and the zucchini plants will gradually age in the later stage. Therefore, in the case of aging or poor growth of the main vine, you can choose to retain two or so lateral vines, appear in the female flowers, cut off the main vines, carry out plant renewal, and promote lateral vines to bear melon.

4. Pick leaves at the right time

When zucchini enters the middle and late growth stage, there are generally a large number of leaves in the lower part of the plant. As a result, the permeability of the lower part of the plant is very poor, which is easy to cause a variety of diseases and insect pests. Therefore, we should timely remove the leaves of the lower part of the zucchini plant to provide permeability and reduce nutrient consumption. However, it should be noted that the petiole water content of zucchini is relatively large, thick and brittle. When removing leaves, the stem is prone to wounds, so when picking leaves, we should pay attention to avoid being infected by bacteria.
