First, the ridge is too low or even ridged. The consequence of this is that the ground temperature is low and the humidity is high, and the root system of the tomatoes is in such an environment. Roots are stunted and even produce root rot. The lighter ones have reduced their production, and the severe ones have lost their production.
Second, fertilization has great blindness. Base fertilizer is too large, nitrogen fertilizer is too much, and organic fertilizer is less organic fertilizer. (Underground chicken and duck manure organic fertilizer, at best, is a bit of nitrogen fertilizer, but also easy to produce ammonia damage, fertilizer damage, salt damage) The direct cause of tomato leaf hypertrophy and leaf hypertrophy is excessive nutrient growth. Tomato fruits have slow growth and do not open; soil organic matter content is low; mineral conversion rate is low, resulting in low fertilizer absorption rate; Poor sex, the lower part is prone to gray mold serious.
Third, stalks and leaves are unreasonable. Some leaves have poor permeability and some have excessive leaves, causing no leaves on the lower part of the fruit. This is the two extremes: the dense permeability of the leaves, the lack of fruit pumping power in the nutrient shunt, and the easy access to the lower part of the gray mold; the ability to reduce excessive leaf photosynthesis in the bottom of the leaves will also lead to slow slow transfer.
Fourth, improper use of anthers. Different seasons, different weather conditions should use different concentrations of wolfberry anthers. However, the people’s plans to save trouble, a cloudy sunny day, a kind of temperature, it is easy to cause a variety of deformed fruit, or adhesions, or exposed grains, not only affect the value of goods, but also affect production.
Fifth, the epidemic disease of the root rot of the rootworm is indiscriminate. On the one hand, medication is not correct, increasing input costs, and on the other hand delaying the opportunity to miss treatment time will not be able to recover losses. For example, some farmers directly treat root worms as a root rot treatment. Can they be cured? Another peasant household directly burns the roots of the tomatoes because of the high concentration of the medicine.
Sixth, extensive field management. Huge water, big and small, and random control of temperature, caused some tomatoes to be leggy, and some to extinguish flash sprouts, and some to drop flowers.
Seventh, ignore the use of trace element fertilizers. Most farmers only pay attention to the use of large amounts of N, P, and K while neglecting the use of trace elements such as boron, calcium, magnesium, zinc, iron, etc., resulting in serious tomato deficiency, yellowing of leaves, or chlorotic chlorosis of leaves, or severe deformity of fruit. Affect the quality of the fruit.
