The weather is dry, how to water to protect seedlings?

Peach saplings suffer from drought

1. Water wisely!

Break the conventional water management model and change the periodic large watering to multiple and small waterings. If conditions permit, flood irrigation can be changed to seepage irrigation and drip irrigation integrating water and fertilizer. Most peach growers who are unable to do so can change from full-scale watering to alternate row watering. Watering should be done every 20 days in alternate rows. Watering should be light until the soil is wet with water. Create a small space with suitable humidity for the peach orchard, which is conducive to fruit development and growth.

It can prevent the soil from being severely short of water and suddenly pouring a lot of water, causing the soil moisture to expand rapidly and suddenly become dry and wet, causing the peach tree to have physiological disorders, an imbalance in the supply of water and fertilizer, and a large number of cracked fruits. When the peach fruit lacks water in the soil and the space is high, the water loss of the fruit will be greater than the supply and the fruit will not be able to develop and grow normally, resulting in chaff and a large number of fruit drops. Therefore, water must be supplied in a balanced manner to meet the fruit’s demand for water and fertilizer uninterruptedly and continuously.

2. Change periodic fertilization to balanced small amounts and multiple times

The climate is changing, and methods must be changed. Only by changing can we cope with the changes, so as to cope with the consequences of bad weather on peach trees. Influence. Peng Futian, a professor at Shandong Agricultural University, put forward a new concept of water and fertilizer application for peach trees in greenhouses. It became a small amount and multiple times, which can lead to a smooth transition without drastic changes in soil moisture. Problems of this kind will occur, which will be helpful for increasing yields. , improving fruit quality is of great significance. Therefore, when open-field peach trees encounter high temperatures and sustained drought, more attention should be paid to water and fertilizer management, and small and frequent meals are particularly important.

3. Water and fertilizer are integrated into one, indivisible peach trees. It is best to use the flushing method to supplement fertilizer, or first inject it into the ground with a fertilizer gun, and then irrigate 2 days later, or use water and fertilizer integration for drip irrigation and infiltration irrigation. , can be effective quickly. A peach farmer at Linjin Work Station in Linyi County has been fertilizing with a gun for many days. The seedlings are growing slowly and the yellow leaves are gradually increasing.

The reason is very simple, that is, after fertilization, there is no effective rain, and the nutrients stored in the tree have been exhausted. In addition, the soil is highly alkaline, which inhibits the absorption and utilization of iron, zinc, and magnesium elements. The fertilizer itself has a high concentration and is far away from the roots. If it is not watered, it will not work at all, and yellow leaves will definitely appear. If fertilizer is injected into the roots, it is likely to cause root burn or seedling death. Therefore, water should be provided in time to achieve water-soluble fertilizer, water-carrying fertilizer, and water-fertilizer integration to promote the absorption of the peach tree root system and achieve the growth-promoting effect.

I think that the practice of watering first and then applying fertilizer over the years has limited effect on supplementing fertilizer. It is necessary to apply it with water, integrate water and fertilizer, and top-dress first and then water to achieve the best effect.

Suggestion: Eat small meals frequently every 20 days without watering on an empty stomach, which will make your early-maturing varieties grow bigger.
