In accordance with the growth habit of tomatoes can be divided into two categories: a limited growth, up to a certain height, tomato plants from the top, no longer high, the general height of the short than the people; the other is unlimited growth, in the environmental conditions suitable for the field, the plant will continue to grow up to grow higher than the people, like a small tree, some people will be called this tomato, "tomato tree! ". At present, "tomato tree" cultivation only in some horticultural expositions or tourist attractions for landscape display, experts pointed out that by the limitations of the greenhouse, planting tomato tree is currently undesirable, and its popularization and application of the value of small. This is only a brief introduction, for reference only.
Planting tomato trees in the management of the key to grasp two points: one is the growing period can not be sick, the second is to do a good job of physiological control, that is, to ensure that the branches and vines stretching area and the results of the rate to achieve the best balance. Therefore, very strict management measures should be developed, and even seal the lid of the nutrient pool in the tomato base to prevent pathogenic bacteria infestation, pests and diseases to prevent the main, roots and foliage regular application of drugs, the first period to promote the growth of vines, remove all flower spikes and fruits. Tomato tree specific cultivation measures are as follows.
(1) Selection of seedling
Select Jingdan 6 and other varieties, choose sunny greenhouses or greenhouses, built with bricks to become a diameter of 2 meters, 50 ~ 60 cm high round pool, due to the use of soilless cultivation methods. Sowing, seedling management with the general tomato: seedling height of about 20 cm when transplanted in the diameter of 10 ~ 15 cm in the nursery bowl, to be about 50 cm high seedlings can be planted to the nutrient pool, above the trellis, generally 2.5 ~ 2.8 meters high, for tomato branches climbing.
General tomato plants
(2) timely planting
Planting will be slightly cleaned tomato seedling roots of the soil, with a rope or bamboo taro to fix the trunk, planting 1 ~ 3 days after the provision of water, 3 days later, the regular delivery of nutrient solution (fertilizer), generally in the pre-growth period of daytime every 2 hours for fertilizer 1 time, with the tomato plants Lin As the tomato plantation continues to grow, the time for fertilizer delivery increases accordingly, and the interval is shortened accordingly.
(3) Nutrient solution concentration
General requirements for the nutrient solution pH 6.4~7.5, conductivity with plant growth (from seedling to fruiting) in the range of 0.6~3.2 gradually increased. Nutrient solution formulations can be used for tomatoes in general and then configured with local water quality.
(4) Branching and pruning
Preliminary stage is mainly to cultivate the main stem, generally stay 3~4 branches, the rest removed, so that the branches of the vertical and horizontal distribution of the growth of an even distribution of the flower spike at this time should be removed as early as possible, to be the more luxuriant branches and leaves, covering a larger area to stay in the flower to protect the fruits, and the branches are lined up to the pre-prepared trellis to make the Fruit spikes evenly distributed on the trellis, and then remove the excess branches, so as not to shade each other. The fruiting spikes will all hang downward, forming a beautiful frame shape.
(5) Pest control
Pests and diseases are prevention-oriented, strengthen the root system of disease prevention measures, regularly irrigate the roots with carbendazim, root rot and so on; the above ground part of the 70% metribuzin wettable powder, 75% chlorothalonil wettable powder, etc., sprayed regularly at a concentration of 800 to 1000 times to prevent disease. According to different pests occurring period spraying corresponding insecticide. Apply a small amount of carbendazim to the wounds of the pruned branches on sunny days to prevent the wounds from being susceptible to disease, spray the whole planting environment with disinfectant for 10~15 days, maintain ventilation and light penetration, and remove the diseased plants in time.
