Carob beans are plants that bloom and bear fruit continuously. If you want to make carob beans grow more, you must first make the carob beans have more flowers, and secondly, prevent premature aging of carob beans. If you do these two things well, then the carob beans will grow longer. It can continue to bloom and bear fruit, thereby achieving high yields. Below I will focus on these two points, from planting to pest control, to talk about how to make beans grow longer!
1. Do a good job in pre-flowering management to lay the foundation for more flowering
Pre-flowering management work is centered around more flowering, which mainly includes fertilizer management and seedling management. Aspects:
1. Reasonable application of base fertilizer
We all know that base fertilizer is the basis of annual nutrient supply, and it is also the main source of early nutrient supply. Therefore, we must pay attention to the reasonableness of the base fertilizer. Organic fertilizer: For the application of organic fertilizer, the more the better, but we have to consider an input-output ratio. It is generally recommended to apply 2,500 to 3,000 kilograms of decomposed organic fertilizer per mu. Compound fertilizer: Compound fertilizer is a difficult choice for our vegetable farmer friends. In fact, legume crops all belong to the fruit and vegetable category. Therefore, their fertilizer requirements are similar. The requirements for base fertilizers are all suitable for low nitrogen, medium phosphorus, and high potassium. It is recommended to apply 30 kg of compound fertilizer per mu with a ratio of nitrogen, phosphorus and potassium of about 10-15-22. Medium and trace element fertilizers and bacterial fertilizers: Bean is a calcium-loving crop. When applying base fertilizer, don’t forget to add calcium fertilizer. If it is chelated calcium, apply about 200 grams per acre. If it is ionized calcium, apply about 5 kilograms per acre. In addition, , if conditions permit, some soil-improving biofertilizers can be appropriately applied, which will also promote yields.
2. Pre-flowering seedling management is the basis for high yield and prevention of premature aging
The focus of management during this period is to water the first three water well. Many vegetable farmers are more casual about watering in the early stage. , in fact, this is a misunderstanding. The quality of the first three waterings determines the later yield in a certain sense. Because if these three waterings are done well, the roots and plants will grow stronger, and there will be fewer problems in the later stages, especially premature aging. Planting water: Planting water not only promotes the survival of seedlings, but also improves the soil. Therefore, when pouring water for planting, it is recommended to apply biological fungicides with the water to improve the soil. Seedling-slowing water: After the beans have slowed down, we need to pour seedling-slowing water. This period is an important period for the differentiation of bean flower buds. Therefore, we must pay attention to the flower promotion work during this period. We can apply some water with the water. For functional water-soluble fertilizers that promote flowering, the recommended ratio is about 12-15-13, and the dosage per acre of land is 2 to 3 kilograms. Water before flowering: Water before flowering must be poured heavily, because the next watering time will not be until after the first crop of beans is picked. In order to prevent water shortage, the water must be poured enough this time. When watering the flowers before watering, you can also apply 1 to 2 liters of rooting water-soluble fertilizer.
By paying attention to the first three water sources, while improving the soil, it also creates favorable conditions for the growth of bean seedlings. Both the root system and the growth potential have been greatly improved. Flower promotion can promote early and good flowering of beans, which lays the foundation for high yields in the early stage. At the same time, the plants have good growth potential and good root absorption, which also creates favorable conditions for preventing premature aging in the later period.
2. Beans should pay special attention to preventing dead seedlings
Bean has the weakest root system among fruit and vegetable plants, so it is easy to be infected with root diseases and cause dead seedlings, causing the roots of dead bean seedlings. Diseases include root rot, damping off, fusarium wilt and anthracnose. Therefore, the prevention and control of these diseases is particularly important. We can solve the problem of dead seedlings in two steps. Step 1: To disinfect the soil before planting, 500 grams of trichloroisocyanuric acid or other strong oxidants can be applied with water. When disinfecting soil, the bigger the water, the better, so that the effective range of the agent will be larger. Step 2: After slowing down the seedlings, irrigate the roots. Adjust the spray blade on the sprayer to spray and irrigate the roots. It is recommended to use oxamethane+thiram+thiophanate-methyl for plots where soil-borne diseases are not serious. Root irrigation is enough. For severe plots, it can be sprayed twice every 15 days.
In addition, while rooting, you can add some organic water-soluble fertilizer for rooting to stimulate the beans to take root and give them a strong root system.
3. Adjust the seedlings during the climbing period to promote high yield
For beans, adjusting the seedlings during the climbing period is very important, because this period is when vegetative growth turns to reproductive growth. During the transition period, there are two tasks that require special attention. One is to control the growth of seedlings, and the other is to promote flowering. Of course, these two tasks can be carried out simultaneously.
When the climbing frame reaches about 60 cm, you can spray fentrileol + flower-promoting water-soluble fertilizer on the leaves. fentrileol can regulate the growth of the seedlings and can also prevent some fungal diseases. It can be done once every 10 days or 2 to 3 times.
By adjusting seedlings and promoting flowers, we can fundamentally solve the problem of weak carob flowers and difficulty in pollination, because carob itself is a butterfly-shaped flower and has the characteristics of difficulty in pollination.
4. Water and fertilizer management is critical
After completing these preliminary tasks, we do not recommend watering and fertilizing before the first crop is harvested. The watering and fertilizing after the first crop is harvested should be watered three times as a cycle, and each application of fertilizer is also very particular. For the first watering, use balanced fertilizer for top dressing, about 8 kilograms per acre of land. For the second watering, apply root-nurturing fertilizer with the water. For the third time, water to promote flowering. The ratio of fertilizers to promote flowering is as mentioned above. Fertilizer ratio for seedling water. Three times is enough for a cycle.
5. Return to seedlings in the mid-term to prevent premature senility
Starting from the first crop, usually within one month of continuous picking, beans will more or less show signs of premature senility, such as the lower part of the plant starting to appear. Yellow leaves, etc. If these symptoms appear, it reminds us to prevent premature aging as soon as possible. High-nitrogen fertilizer and calcium fertilizer can be applied once with water. The recommended dosage of high-nitrogen fertilizer is 10 kilograms per mu, and the dosage of calcium fertilizer is 4 kilograms per mu. While supplementing the soil with nutrients to promote the return of seedlings, it should also be sprayed on the leaves. In this way, the above-ground parts Combined with the underground part, the problem of premature seedling aging can be well solved.
6. Prevent diseases to ensure yield
Bean diseases are less common, but not impossible. Therefore, it is necessary to prevent diseases to ensure yield. In plant protection, we all demand that prevention is better than cure. Disease prevention: Prevention can be achieved by spraying the package of difenoconazole + pyraclostrobin on the leaves, which can have a good preventive effect on all diseases. It is recommended to spray it every 10 days to half a month. once. Prevention and treatment of diseases: For advanced fungal diseases, such as powdery mildew, anthrax, rust, etc., the drug thiram + thiophanate methyl + difenoconazole can be used; for gray mold and sclerotinia, boscalid can be used +Bacillus subtilis for treatment.
These tasks are all management measures centered on flower promotion, seedling conditioning, preventing premature aging, and preventing pests and diseases. If these tasks are done well, the yield of snap beans will be greatly improved. If used well, it can be said that there is no problem in increasing the yield by more than half, because beans are one of the vegetables that are easiest to increase yield.
