What technology was invented by an American farmer 1929?

Soilless culture technology was invented by an American agronomist in 1929. It can not only accelerate the growth of plants, but also make them tender green, so that we can eat fresh vegetables in winter.

Cucumber, alias zucchini, zucchini and zucchini, is an annual climbing plant of Cucurbitaceae. It is one of the favorite vegetables of urban and rural people, especially in recent years, because of the production of pollution-free vegetables, cucumber is increasingly favored by people. In addition, the variety types are rich and adaptable, so they are widely distributed.

Variety selection

In greenhouse production, our selection requirements for cucumber varieties are: varieties with infinite growth type, low female flower node (preferably pure female line), straight melon strips, excellent quality, high yield and strong disease resistance. Among them, cucumber is generally resistant to high temperature and strong light in summer and low temperature and weak light in winter. According to the different climatic conditions and planting time, choose the varieties that suit you.

grow seedlings

For the cultivation of self-rooted seedlings (non-grafted seedlings), please refer to < < plug seedling technical operation specification > >; . For the plots where cucumbers are planted all the year round, because of continuous cropping, cucumber root diseases are more and the soil salinization degree is higher, so grafted seedlings are used in many places now, among which white seed pumpkin is used as grafting rootstock. Grafting generally adopts splicing method.
