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 />
