1. How to cut watermelon?
The watermelon will be split according to the growth of the watermelon. Generally speaking, there are 4 stages of splitting:
1. Under the normal circumstances of watermelon growing for about 20 days and performing one-stage slicing, the watermelon will survive about 10 days after planting. Watermelon seedlings that have just survived have a process of adaptation to soil, environment, etc. At this time, the melon seedlings are very fragile and cannot be immediately manipulated, such as splitting and topping. After the melon seedling grows to about 20 days, it begins to grow a lot of branches. At this time, we need to break the watermelon in one stage. This stage of the branch is also called "pinch", which refers to the main watermelon. Remove the top, leaving melon seedlings with only 4 side vines or 4 leaves.
The purpose of the watermelon's one-stage breaking is to remove the top advantages of the melon seedlings, promote the growth of four lateral vines, and concentrate nutrients to the roots of the watermelon, so that the roots of the watermelon can accumulate and store more nutrients to improve the melon The stress resistance of seedlings can prevent melon seedlings from becoming stiff and dead.
Supplementary note: The watermelon only needs to be beaten once in the first stage, that is, only "pinch" once, that is, the top of the main vine can be removed. Remember not to remove the top of the side vine. Otherwise, it is not conducive to the growth of watermelon leaves, it is not conducive to the expansion of watermelon.
2. Two-stage splitting is carried out after the watermelon has grown for about 30 days. Because the top edge of the watermelon main vine is removed, the melon seedling will supply nutrients to 4 side vines after pinching the tip. The 4 side vines will grow rapidly, generally at 10 It can grow to 20 cm in about days. At this time, we need to perform two stages of foraging the melon seedlings, that is, removing two weakly growing side vines with disease and insect pests, leaving two thick branches as watermelon. As a result, the fruit of the watermelon grows on these two lateral vines.
The purpose of the two-stage watermelon bifurcation is to determine the number of watermelon vines, and to ensure that nutrients can supply the remaining two growing vines, and promote the growth of melons. At the same time, make these two growing vines have long leaves and accumulate nutrients. And prepare for the watermelon to bloom and bear fruit.
Supplementary note: The two-stage cutting is also called pruning, which is the double-vine pruning method used by melon farmers in the past two years. Therefore, the watermelon in the second stage only needs to be beaten once, that is, in the second stage, the two weakly grown side vines are removed from the four vines, leaving two strong side vines.
3. Perform three stages of twig melon seedlings before the watermelon leaves melons. After determining the number of melons, with the continuous supply of nutrients, twigs will grow on each leaf, and these twigs will consume a lot of nutrients. At this time, it is necessary to split the watermelon in three stages, that is, to break off all the newly grown branches on the two side vines, to prevent the branches from consuming nutrients and affecting the watermelon blossom and fruit setting.
The purpose of three-stage watermelon branching is to reduce the consumption of nutrients by the branches, so that the nutrients are concentrated on the flowers, fruits and growing vines of the watermelon, while ensuring that the growing vines grow thick, and promote the growth of watermelon flowers and fruits, and Improve the pollination rate and fruit setting rate of watermelon to prepare for watermelon retention.
Supplementary note: In order to improve the photosynthetic efficiency of watermelon, promote watermelon to expand rapidly after leaving melon. We generally need to wait for the watermelon's side vines to grow about 20 leaves before they start to retain melon (watermelon grows for about 60 days). Therefore, the watermelon needs to be beaten 3-5 times in three stages, and the interval between the front and back is not recommended to exceed 6 days. In addition, when the watermelon is split in three stages, we have to pick off the melons and young melons together.
The reason why the melon must be removed is that the melon must be left will cause the melon and vine to grow together, and there will be a "string vine" phenomenon, which is not conducive to our subsequent management. The reason why young melons are to be removed is because the melons formed by the watermelon before 20 leaves are easy to form zucchini. Such melons will only waste nutrients in vain, and will not grow.
4. After watermelon leaves melon, carry out 4 stages of watermelon splitting. After determining to leave melon, we usually mark it well to prevent confusion with watermelon that has not been "flowered". However, with the growth of melons and vines, many branches and young melons will still grow on the growing vines of watermelons. This requires us to perform four stages of watermelon branching, that is, the branches and leaves above the "reserved melon". Young melons are removed.
The purpose of the four-stage watermelon twitching is to promote the expansion of the watermelon, to concentrate the supply of nutrients to "retain melons", and promote the high yield of watermelons, while avoiding the occurrence of stiff, crooked, and cracked melons due to insufficient nutrients after the "retained melons" And other phenomena.
Supplementary explanation: With the gradual enlargement of "retaining melons", a lot of nutrients will be consumed. At this time, the growth rate of melons and vines will slow down, and the speed of branching will also slow down. Therefore, watermelon only needs to be beaten 2-3 times in 4 stages.
Special reminder: Many novice melon farmers will pinch off the top of the side vine after the watermelon leaves the melon. This is wrong. Once the top of the seedling is pinched, a lot of nutrients will flow to the "leave melon", which is easy to put "Retaining melons" can cause melon cracking. In addition, the top of the melon seedlings is pinched, and there will be no new melon nodes, so we can not guarantee the yield of 2 crops and 3 crops.
2. What are the precautions for watermelon breaking?
1. Farmer friends who have worked hard to plant watermelons in greenhouses know that the temperature in the greenhouse is high and the temperature difference between day and night is large. The branches of watermelon grow relatively quickly. Under normal circumstances, they can grow up to 10 centimeters a day. In order to prevent the nutrients in the soil from being consumed by the branch, and to promote the high yield and high quality of the watermelon, we must destroy the branch before it grows up, especially when it is split in the second stage, we must pay attention to it at any time The growth of the branch, once the new branch grows, it should be immediately destroyed, because the new branch is relatively vigorous, and the ability to absorb nutrients is relatively strong, which easily affects the growth of watermelon fruit and side vines.
2. Abandoned branches and leaves centralized management Many melon farmers like to throw the freshly-branched branches into the melon field to save trouble, in fact, this approach is wrong. Abandoned branches and leaves are relatively weak, and they are likely to carry some bacteria and insect eggs. In addition, the temperature in the shed is high, and it is easy to breed pests and diseases. Once we discard the abandoned branches and leaves, the bacteria and insect eggs will spread. And threaten the normal growth of watermelon plants. Therefore, we must take the abandoned branches and leaves out of the shed, and burn them down and bury them in a concentrated manner.
3. Don't water the watermelon immediately after breaking it. Watermelon belongs to water-loving crops, and the requirements for water are very high during the whole growth process. However, after the watermelon is twiged, it cannot be watered immediately. There are two main reasons:
One is that watermelons need to recover slowly after being split, and during the watering process, it is possible to let water droplets fall on the parts of the watermelon and cause wound infections. This is just like we were injured and it is a reason that we cannot touch the water;
Second, the watermelon will increase the humidity in the shed after watering, and the temperature in the greenhouse is already high. In the high temperature and high humidity environment, it is easy to breed various diseases and insect pests, and the watermelon is weaker and easier after the fork Let pests and diseases take advantage of the situation.
It can be said that the twig is a decisive factor for the yield of watermelon. Watermelon does not grow very large, or there are zucchini, cracked melon, etc., probably caused by improper twig.
