Secondary fruiting cultivation techniques of Tomato

The improved varieties of tomato hybrids have obvious advantages in production, and their yield, quality and disease resistance are higher than those of ordinary varieties. However, the production of hybrids is time-consuming and time-consuming, and the technical requirements are high, so the seed price is higher. In order not to change the characteristics of the original variety, but also to arrange the stubble and shorten the growth period, and to reduce the production cost, the secondary fruit technology of tomato was studied. The secondary result steps of tomato are introduced as follows:

[mid-term bifurcation]

Leave a common branch (small frame variety) in the first third ear, if the production of the branch is strong and affect the pollination and fruit setting at the flowering stage, it is necessary to pick the growing point to promote the normal growth of the flower. The varieties of medium and large shelves are kept between 4 murals and 5 ears, and the management is the same.

[keeping seedlings in the later stage]

In the later stage of tomato growth, adventitious twigs appeared, at this time, strong growth, dark green leaves, short internodes, obvious buds were selected for culture, and others were removed.

[to grow new plants]

Cut off the original plant 5 centimeters from the ground with scissors, then irrigate and top fertilizer (12.5 kilograms of urea per mu). About 5 days, grow small branches, choose the good to the bad.

The key points of comprehensive management of tomato secondary fruiting cultivation are as follows: due to the consumption of more nutrients in the early stage, we should be diligent in water and fertilizer, that is, watering water every 5 days, topdressing dilute dung or diammonium (15kg / mu), or applying sesame sauce cake (100kg / mu) and sprinkling it in the ridge. In the middle stage, quick-acting fertilizer can be applied, such as ammonium sulfonate (25 kg per mu) or ammonium nitrate (1.25 kg per mu), combined with foliar spraying fertilizer (0.2% potassium dihydrogen phosphate or 10 ml Yemanbao per mu). At the same time, attention should be paid to preventing the occurrence of diseases and insect pests such as epidemic diseases, anthrax, viruses, cotton bollworms and aphids.
