When the author interviewed Dongjia Village in Luocheng Street, the village's sister Shao told the author that the two lettuces had been harvested and are now ready to be grown. For the income of two lettuces, Shao Sister is still quite satisfied.
“The total output of the two lettuces is about 12,000 pounds, and the average price is close to 2 yuan. This is not too much to earn, but considering the low input costs, labor savings and labor, plus there is a bean, such benefits It is still good.” Sister Shao said to the author of the Agriculture and Forestry Network.
Where are the management priorities of the two lettuces?
Reasonably arrange the growth space for lettuce
The focus of lettuce consumption is on the thick leaves, which requires the vegetable growers to rationally arrange the growth space for lettuce, leaving more room for lettuce leaves to grow around, rather than planting as much as possible.
Sister Shao chose a row spacing of 40 cm for planting seedlings and the results were good.
Temperature control should be properly
Lettuce likes cold weather, good tolerance for low temperature weather, therefore, vegetable farmers are more relaxed about the lettuce shed management, but low temperature does not mean that does not require insulation, generally when the outside temperature is low to minus 4 °C, coverage Grasshoppers are already necessary for heat preservation, which can prevent frozen lettuce from freezing and increase the growth rate of lettuce so as to raise the market in the morning.
Watering control, pay attention to disease prevention
Lettuce management is relatively simple, simple to the entire growth period, only two water can be poured, generally after the flooding of the planting, after planting for 4 to 5 days for the second watering, watering can not be overworked, both to avoid rot The situation occurs and it prevents the long culms of lettuce from growing.
As lettuce grows over the winter, the humidity in the shed at this time is relatively high, so the disease can be prevented. In the early stage, it is necessary to pay attention to cultivating strong seedlings, and spraying fungicides in time to prevent and treat diseases, so as to avoid the phenomenon of rotten trees and rotten leaves. Later, with the extension of the blade, the difficulty of spraying is increased, and because the humidity of the greenhouse is controlled because the water is no longer watered, spraying is generally not performed.
