In the technical chain of tomato cultivation, the choice of varieties is a determining factor for success and effectiveness. Many farmers and park producers are often beset by a number of questions in their choice of varieties: how do we choose the varieties suitable for local cultivation? Here's a little bit of a lesson on how to choose a good tomato seed。
When looking at the performance of the varieties, the vegetable needs to capture the following:
- it's early
The varieties of tomatoes that are suitable for early spring planting are well-developed, well-regulated and mature varieties. The price of vegetables in the spring is high to low, and prices may vary by more than one dollar per pound, three or four days late on the market。
Second, it's more resistant to disease
With the increasing weight of tomatoes, the incidence of diseases is increasing, seriously affecting the production and quality of tomatoes. The price of tomatoes has stabilized since this year and is highly correlated with the growing incidence of viral disease, the death of a tree, the decay of a leaf and all kinds of folic disease. There is a marked decrease in the incidence of diseases when the variety is highly resistant to disease and the conditions of birth are good. The choice of resistant varieties requires the attention of vegetable farmers in order to reduce the risk of planting and to reduce management difficulties。
Three is market demand
The species preferred by consumers, including the shape, colour, hardness, etc. Of tomatoes, the selection of seeds from national research institutes, large and qualified enterprises, and the selection of suitable varieties based on different outlets。
I'm picking tomatoes every season
Early spring cold room tomatoes
One word, "early", is tomato. And it was said: "shall i grow earlier?" early spring cultivation is subject to temperature constraints and some varieties are not suitable for low temperatures, so pre-cooked varieties are chosen. The tomatoes have seven leafs and nine leafs, and choose the seven leafs. If you sow a seven-leaf sit-in fruit on the same day, it's 10-15 days in the city. Also, varieties with short growth periods of fruit are selected, from flowering to maturity for 40 days in normal years, for 50 days, for 40 days. The view was expressed that the variety was large, yield high and income high. In fact, in the early spring cold-garden tomatoes, each of which leaves four ears, usually acres produce between 0. 75 and 10,000 kilograms, and large varieties are usually very old, and if they mature too late, the price of the tomatoes is low and thousands of pounds more are not sold。
The vietnamese tomato
In may, yuzhmorgeologiya tomatoes were usually bred, and the mouth of the tomato was brought on the market at high temperatures and rainy seasons, and the field was characterized by a large number of cleavages, severe diseases, fruit colours and quality, which did not match those produced in the shed. The poaching of tomatoes is a three-voltage period, so the heat-resistant species are chosen. When buying seeds, no manufacturer will tell you the exact heat-resilient temperature, because heat-resistance is itself a vague concept. The temperature at which tomatoes grow normally is 25°c ~ 30°c over a long period of time, the flowerer of the tomatoes is abnormally developing, forming deformed flowers, producing deformation fruit, and more than 35°c pollen quickly depletes, so none of the varieties are really resistant to heat, which is determined by the characteristics of the tomatoes. Some physical protection measures may be taken against summer heat, with the choice of a strong, leafy variety to protect against solar fever。
Autumn delayed tomato
The tomato is normally sowed in june, during which time emphasis should be placed on the occurrence of a yellow loaf virus. Because celibate curvitis can lead to crop failure, the best way to combat eutrophication is to choose the varieties of tomatoes that are resistant to cedars. When it comes to anti-yellow trafluorine varieties, many consider that foreign varieties are better than domestic varieties, because the hardness is higher than that of domestically produced species, and the hardness varieties are suitable for export and, if internalized, for national products. Moreover, many foreign varieties require seeding after july because of poor heat tolerance, prolonged development of tomato fruit and poor performance if the autumn is delayed and cold sheds are planted, lawyers from guangdong and fruit grow long, affected by lower temperatures in the autumn, low commodity fruit rates and high seed prices。
In autumn, greenhouses are delayed and domestic production and imported seeds are available, since early and late ripening is no matter, and is a light season for tomato supplies。
