A, scaffolding and pruning

When the seedlings grow to about 20 cm, it is necessary to set up a frame to draw vines. Generally, you can choose flat shed frame and herringbone frame.

Liandongping scaffolding is generally in Guahang, and stakes are erected. The stakes of the whole field are connected with small bamboo poles and wooden sticks, and the roof is about 2 meters from the ground. Shed height 1.5 ~ 2m. Scaffolding should be firm, so as not to collapse due to wind, damage seedlings and affect yield.

Second, intertillage, weeding and soil cultivation.

Generally, after planting, a intertillage is watered with slow seedling water. The second intertillage was carried out 10 ~ 15 days after the first intertillage. Every intertillage can be combined with some high-quality farmyard manure, such as cake manure, all kinds of poultry hair, decomposed chicken manure, pig manure and so on. Clear weeds in time during intertillage. If missing or weak seedlings are found, replanting should be done in time to preserve the seedlings.

Third, water and fertilizer.

It is better to apply water and fertilizer topdressing, and the principle of fertilization is diligent fertilization and thin fertilization. After flowering and fruiting, topdressing can be done once, and then topdressing 1 time every 7 days during the picking period of melon can prolong the picking period of melon. ?

Fourth, pests and diseases.

600 times of chlorothalonil powder can be used to control powdery mildew, and trichlorfon can be used to control pests such as Drosophila melanogaster and Spodoptera litura.

The selection of bitter gourd varieties is more important. Good varieties have high yield and good taste. Don't ignore it. If you want to plant bitter gourd to achieve high yield, you should strengthen field management such as shed pruning and pest control. The above are the detailed techniques of scaffolding, pruning, weeding and ridging of bitter gourd planting, which you can learn from.
