There are a lot of friends who plant beans, tomatoes, and peppers every year, although many people like to plant, but there are not many people who can really manage the high yield, because vegetables like beans, tomatoes, and peppers will have many problems in the growth, such as: all kinds of pests and diseases, less fruits, falling flowers and fruits, dead trees and rotten roots, etc. Most of the causes of these problems are related to watering, fertilization, and management. Therefore, when planting beans, tomatoes, and peppers, you can't water them indiscriminately, and you can't fertilize them indiscriminately, otherwise you will be prone to problems, so let's take a look at them together.
Beans
Watering: Beans are planted in the process, watering is very critical, beans are a crop that is most afraid of waterlogging, especially before flowering, if watering too much, not only the leaves are easy to yellow, but also easy to cause the branches and leaves to grow faster, resulting in less flowering.
There are several principles for watering beans: one is to keep the soil slightly dry before flowering, as long as the soil is not particularly dry, try to water as little as possible, even if it is watering, it must not be flooded with large water, and it should be watered slowly with small water. Second, after the beans begin to grow, the soil must be kept moist and not too dry, but the soil must not accumulate water, which will lead to the death of seedlings.
Fertilization: carob fertilization is different from other crops, if the bottom fertilizer is used during planting, do not carry out top dressing before flowering, if there is no bottom fertilizer, the seedling stage can be used to apply a little seedling fertilizer, but can not be used too much, if there is too much fertilizer before flowering, it will inevitably lead to the growth of seedlings, and carob is a crop that is most afraid of the growth of seedlings. So, try not to top dressing before flowering.
The best time for top dressing of beans is to carry out top dressing when starting to set beans, and the fertilizer can choose balanced fertilizer, organic fertilizer water, etc. for watering and flushing, and the foliar surface can be supplemented with molybdenum fertilizer, boron fertilizer and other fertilizers.
tomato
Watering: Tomatoes have a characteristic, they are easy to root when watered more, and they are easy to get viruses when they are drought, and watering is really difficult to grasp. Therefore, it is important to plant tomatoes well and water them well, and the soil should not be too wet before flowering, and it should be kept dry to promote deep rooting and lay the foundation for later fruiting. After the fruit is moistened, do not use large water to irrigate, and keep the soil breathable, simply put, tomatoes from the seedling stage to the fruiting stage, can not be watered too much and too often, to do not dry and do not water. If the weather is dry, you can often spray the leaves with water and some amino-oligosaccharides to prevent viral diseases.
Fertilization: Tomatoes have a long growth period, in addition to the use of base fertilizer, but also to carry out top dressing, top dressing is generally carried out at the seedling stage and after fruiting, and it is not easy to fertilize at the early flowering stage. Fertilizing tomatoes should ensure that the nutrition is comprehensive, especially in the fruiting period, neither potassium fertilizer nor nitrogen fertilizer alone, nitrogen growth, potassium to promote fruit, lack of which is not good, nitrogen, phosphorus, potassium and various trace elements can not be less. Under normal circumstances, the roots are mainly nitrogen, phosphorus and potassium, such as well-rotted organic fertilizer, balanced fertilizer, etc., and the foliar supplement of trace elements, such as boron fertilizer, calcium fertilizer, etc. to ensure that the growth of branches and leaves and the flowering and fruiting are not affected.
chili pepper
Watering: Peppers are not drought or waterlogg-tolerant, and are very strict with moisture like tomatoes, and when drought and overwatering, they can lead to leaf drop, flower drop, and fruit drop. In addition, if there is water in the soil where the peppers are grown, the seedlings will wilt or even die. Therefore, peppers should not be grown with too much watering or too much at all times, and drought should not occur. Especially during the flowering and fruiting period, you can not use large water to irrigate, and when the soil is dry, you can use small water to water it slowly. Again, in the rainy season in summer, it is necessary to strictly prevent excessive soil moisture.
Fertilization: pepper fertilization and tomatoes are almost the same, seedling fertilizer can be applied at the seedling stage, and fruit promotion fertilizer can be applied after fruiting, but must not be fertilized at the beginning of flowering, and high-concentration fertilizer and raw fertilizer can not be used, nor can it be fertilized at noon in high temperature weather, in order to prevent flower and fruit dropping. Fertilizers can be thin balance fertilizers, organic fertilizers, etc., and nitrogen fertilizers should not be used alone. The foliar surface can be supplemented with boron fertilizer, phosphorus and potassium fertilizer and trace elements during the pre-flowering and fruiting period.
Therefore, whether it is watering or fertilizing, it must be flexibly controlled according to soil moisture, crop growth, etc., and cannot be arbitrary.
