At present, vegetable consumption in Shanghai is in the stage of transition from quantity to quality, and freshness is also an important indicator of vegetable quality. In order to allow the public to eat fresh seasonal tomatoes in late April, Zhou Jinnan, an agronomist at Bay of Rivers in Baoshan District, has successfully developed the technology of early precocious tomato cultivation after years of hard work and has received good social and economic benefits.

It developed to 393 acres in 1989 and the mu production value reached about 1635 yuan by the end of May. (A) the selection of special precocious varieties Early maturing tomato harvest must be listed on the field of early maturing tomatoes before they can sell a good price, high efficiency. Therefore, my choice of anti-TMV yellow short yellow × 402 and 6T × 402 two varieties. And according to the growth of tomato grasp the sowing and transplanting period. Short yellow × 402 tomatoes from flowering to mature generally require 40 ~
