The latest course of field management techniques and methods of pumpkin

Pumpkin has a long history and is widely cultivated all over the world. it is one of the earliest cultivated crops of human beings. after emergence, pumpkin can obtain high yield and improve income by strengthening field management. So how to manage pumpkin cultivation? Let's have a look with the editor.

1. Seedling stage management

After the seedlings are unearthed, it is necessary to loosen the soil in time to promote the root growth of the seedlings, and be careful not to damage the roots. Weeding should be carried out at the same time in mid-tillage, weeds will occupy the nutrients and growth space of seedlings, and in serious cases, it will cause grass shortage and affect the growth and development of seedlings. Weeding suggests manual weeding, poisonous pesticide weeding can be selected when planting in a large area, in addition, weeding should be done according to seedling growth height and time when weeding in the middle tillage, and poor growth, disease and insect seedlings should be removed and strong seedlings should be retained during interseedling. It is necessary to strengthen inspection after the seedlings to check the survival rate of the seedlings, and to replenish the seedlings in time once the dead seedlings are found.

2. Pruning and pressing vine

When the melon seedling grows to 4-7 true leaves, it is necessary to pick the heart in time to promote the inverted vine to produce lateral vines. Generally, in addition to the main branch, only 4-5 strong lateral vines are left, and the rest should be removed. When the melon vine has 40-70 cm, it is necessary to draw the vine to press the vine once, which leads the vine to the middle of the row and opens a trench on the ground at the top of the vine to press the vine, which can promote the pumpkin stem node to grow adventitious roots and increase the absorption area of the root system. and a fixed role.

3. Fertilizer and water management

After slowing down the seedlings, if the soil is dry and wet and the weather changes, it should be watered more in sunny days, but not in cloudy days or less, while sandy soil should be watered more in order to prevent soil hardening. It should be drained in time in rainy days to prevent the roots from stagnant water and rot. When the plant has borne fruit, in order to promote fruit expansion and multi-fruit, if there is no rain, it should be watered in time. On the other hand, pumpkin needs less fertilizer at seedling stage, and topdressing can be watered with light dung water or urea solution one week after planting. After the plant is fruited, it is necessary to apply expanded melon fertilizer in time to promote fruit expansion and multi-fruiting, applying 10 kg ammonium bicarbonate and 10 kg potash fertilizer per mu. After the first harvest, 300 kg of topdressing fertilizer per mu and 20 kg of ammonium bicarbonate per mu can prevent plant premature senescence and promote subsequent melon growth.

4. Pest control

In pumpkin planting and production, diseases and insect pests are the key points that harm the yield and quality of pumpkin. Pumpkin Zhu'ayo disease has quenching disease and root rot disease, which can be controlled by carbendazim. The main pests are crickets, snails and other underground pests, which can be controlled by insect buster and ground insect, while snails can be controlled by snail nemesis and coal waste.
