In tomato plant, due to the improper management of certain, often result in premature aging phenomenon, seriously reduce the economic benefits of farmers friends.Tomato premature aging, then, what reason be?Tomatoes premature aging?This article will guide you along to find out the reason for the tomatoes premature aging and preventive measures:
Tomatoes premature aging
1, the continuous cropping obstacle cause premature aging.Facilities conditions of greenhouse tomato due to the limit, often years continuous cropping, years of continuous cropping, soil harden, plant diseases and insect pests is serious, affect the normal tomato root growth and absorption of nutrients, leading to premature aging tomato.
2, excessive control long cause premature aging.Seedling early or late preceding vegetable harvested in seedlings not colonize in time, the age of seedling is too long.So, some farmers in order to inhibit the growth of seedlings, adopt measures to control and water, reduce the temperature, the result is likely to form small old seedlings, lead to premature aging tomato.
3, prevent improper cause premature aging.One is to take off the fat cause premature aging.Such as excessive soil drought, restrain the growth of seedlings, do not pay attention to water management, result in tomato fat off dehydration.Second, do not pay attention to the application of organic manure, one-sided to add fertilizer, soil harden and permeability decrease, affect the root growth and development, cause premature aging tomato.3 it is one-time excessive fertilizer application, soil density increased, root growth and lead to premature aging.
4, hormone use undeserved cause premature aging.In the greenhouse tomato cultivation, especially in the autumn of delayed cultivation, due to the early stage of the temperature on the high side, inside the greenhouse humidity is big, if planting density, water management, temperature control measures such as improper, vulnerable to tomato moderate growth.Moderate growth, some farmers are more convenient to control tomato, often used to spray multi-effect azole, short form element, helps the CCC, such as hormones, to control the moderate growth.But in the use, if the concentration is too large, or repeated drug use, form aging miao extremely easily, cause premature aging tomato.
Tomatoes premature aging preventive measures
Pay attention to the water
Tomatoes in moist soil, so want to timely watering, keep the soil see dry wet, don't let the water again after the soil is too dry, dehiscent fruit and premature aging phenomenon happened so easily.
Reasonable fertilization
Reasonable fertilization is to provide nutrients for plant growth, an important measure to prevent premature aging of the plant.But avoid by all means is too much fertilizer, in order to avoid root damage, leading to premature aging.
Control the long steep
Because PengShi cultivate tomato suitable temperature and humidity, prone to moderate growth phenomenon.So as soon as possible regulatory environment and spraying plant growth regulator control plant moderate growth.
The use of foliar fertilizer
Timely use of foliar fertilizer supplement of trace elements, to prevent a variety of physiological disease caused by deficiency, cause plant premature aging.
Timely prevention and control of plant diseases and insect pests
Tomatoes common diseases are as follows: morning and evening, leaf mildew, virus disease, bacterial leaf spot, mould, etc., pests are: mealworms, spot hidden rope, thrips, aphids, etc., to early prevention and treatment, so as not to cause harm, cause premature aging plant.
Appropriate closed early
Proper earlier recovery, reduce the financial burden on the plant, promote the growth of late fruit, and reduce nutrient consumption, avoid premature aging plant.
Diseased leaflets
Sick leaves, old leaves removed in time, increase the rate of ventilation pervious to light, promote plant growth, delay plant premature aging.
