Reducing tomato malformations, these measures need to be kept in mind
The umbilical part of the tomato is a physiological disorder and a kind of deformed fruit. So what is the cause of tomato malformation? The root cause is that the flower buds are poorly differentiated in the early stage, and the deformed flowers are formed. The fruits of the deformed flowers are all abnormal fruits.
The characteristics of the variety are the basis for determining the development of tomato flower and fruit. On the basis of selecting the varieties, the vegetable farmers should also grasp the following three aspects:
Regulate the shed environment
The main factors affecting the flower and fruit malformation of autumn 茬 are temperature and light. At present, there are many high temperature and strong light weathers, which are easy to cause high temperature obstacles and strong light in tomato, and it is easy to cause the seedlings to grow long, the flower buds are poorly differentiated, and the flower and fruit deformity rate is high.
Coordinate the relationship between vegetative growth and reproductive growth
Autumn sorghum tomatoes generally leave six ears or seven spikes of fruit, from the beginning of fruit set to the end of plant fruit set, it is the time when fruit and sorghum grow at the same time. Tomato is a continuous flowering and continuous crop. When the first inflorescence fruit grows, the second, third, fourth and fifth inflorescences develop to varying degrees, especially in the 20 days after flowering, a large amount of carbohydrates are transported into the fruit. Between vegetative growth and reproductive growth, as well as between fruit development and flower bud differentiation, competition for nutrients is more obvious. Once the nutrient supply is insufficient, it will affect the development of several spikes. Therefore, after the tomato enters the fruit setting period, it should be based on high-potassium fertilizer. It can be applied twice with high-potassium fertilizer and a balanced fertilizer to promote fruit-breaking.
Leaf surface boron supplementation, calcium supplementation
Boron fertilizer is beneficial to plant flower bud differentiation, and calcium fertilizer can increase the toughness of pericarp cells and reduce the occurrence of cracked fruit. Therefore, the vegetable grower can spray 600 times of borax or 1500 times of quick-bored boron to mix high-quality calcium fertilizer to promote the normal growth of the fruit setting and fruit of the tomato.

Roundness Measuring Instruments
Roundness meter is a length measuring tool for measuring roundness using the rotary axis method. The roundness meter is a measuring tool for measuring the roundness error of the workpiece using the rotary axis method. Roundness tester is divided into two types: sensor rotary type and workbench rotary type. During measurement, the measured part is installed concentrically with the precision shaft system, and the precision shaft is attached with an inductive length sensor or a workbench for precise circular motion. It is composed of sensor, amplifier, filter and output device of the instrument. If the instrument is equipped with a computer, the computer is also included in the system.Roundness Tester
The principle of the roundness meter is the same as that of the coordinate measuring machine. In fact, its working principle is very simple. The coordinate measuring machine is a point acquisition tool. Its principle is to collect points first, and then form a line from points, and then form a three-dimensional model from lines. CMM is a kind of measuring equipment that has a guiding mechanism, a length measuring element, a digital display device in three mutually perpendicular directions, and a worktable that can place the workpiece (not necessarily large or huge). The measuring head can be moved to the measured point easily by manual or motorized means, and the coordinate value of the measured point is displayed by the reading device and the digital display device. Obviously, this is the simplest and most primitive measuring machine. With this measuring machine, the coordinate value of any point in the measured volume can be displayed through the reading device and digital display device.
