Seedling tray bottom layer under the straw effect is good

Qingjia City, Heguan Town, Qinjia Village is mainly planting summer squash, and now the production of vegetable canopies is nearing the end. Many vegetable farmers began to cultivate seedlings for squash in early spring, and vegetable farmers Zhou Xiaochun is no exception. This is not what the reporter saw in Zhou Xiaochun's greenhouse. The nursery tray was neatly put together and covered with a layer of plastic film. Then he used a mulch to tie up a “small shed” and underneath it, a layer of smash was laid. Corn stalks.

According to the reporter, in the process of using plug seedlings, most vegetable farmers directly put the plug trays on the ground. Zhou Xiaochun introduced that it is very necessary to lay a layer of straw under the plug. It has the following three advantages.

First of all, padding a layer of straw on the bottom of the plug can prevent the roots of the seedlings from penetrating into the soil and reduce the occurrence of root-cutting during movement. If the nursery tray is placed directly on the ground, the root system will extend from the hole in the bottom of the plug into the soil after the hole is full. When the plug is moved, part of the root system will be broken and the root system will be injured. Placing a layer of straw on the bottom of the nursery tray solves this problem.

Second, avoid roots from touching the soil and reduce the chances of soil-borne diseases invading. Directly putting the seedlings on the ground, the roots of the seedlings will have the opportunity to contact the soil as long as the bottom of the seedlings grows. The harmful bacteria in the soil may invade the roots, and there is a layer of straw at the bottom to eliminate this possibility.

Again, it can be used to regulate the environment under the disk. After the straw is placed under the seedling plate, the permeability at the bottom is increased, which makes it easier for oxygen to enter the matrix. After watering, it is not easy to form water at the bottom, which is conducive to the growth of the root system. At the same time there is also a fast warming and good moisturizing properties.

According to Zhou Xiaochun's introduction, using this method to cultivate squash seedlings, from sowing to emergence is 2-3 days ahead of time, we may wish to try.
