Solving the Particular Contradiction<br />
of Onions<br />
Our success in preserving tomatoes gave us confidence<br />
and inspiration to tackle the problem of storing other<br />
perishable vegetables. We experimented with onions.<br />
They are a bulb, very nutritious but apt to sprout, become<br />
hollow and rot when stored for a long time.<br />
To prevent sprouting, we first tried the same method<br />
as for preserving tomatoes, that is, by controlling temperature,<br />
humidity and ventilation. It didn't work. The<br />
onions were all right as long as they were in cold storage,<br />
but they sprouted all the quicker when they were taken<br />
out. We studied Chairman Mao's teaching: "Unless we<br />
study the particularity of contradiction, we have no way<br />
of determining the particular essence of a thing which<br />
differentiates it from other things, no way of discovering<br />
the particular cause or particular basis for the movement<br />
or development of a thing, and no way of distinguishing<br />
one thing from another or of demarcating the fields of<br />
science." With this as our guide, we specifically analysed<br />
the characteristics of onions' changes after they were<br />
picked and found that, different from tomatoes, they<br />
sprouted only after undergoing a dormant period. While<br />
a low temperature could prevent them from sprouting<br />
temporarily, it didn't solve the contradictions fundamentally.<br />
They sprouted as soon as they were out of the<br />
cold storage and in a suitable temperature.<br />
We tried something else. Instead of storing at a controlled<br />
temperature in the cellar, we sprayed a chemical<br />
on the shoots in the field before harvest. Onions thus<br />
treated did not sprout, and storage time could be extended.<br />
Our success with experiments on a small scale<br />
