Fertilization and freezing damage prevention methods for summer mature crops
Summer is a time when agriculture is busy, not only to harvest, but also to plant, which also indicates that summer is the time when crops grow most vigorously, so for different crops, farmer friends must do fertilization and freeze damage prevention work Effectively ensure the high and stable yield of summer mature crops, let's understand together!
1. Fertilization of summer mature crops
1. Deep application of bottom fertilizer should be moderate
After the summer crops are planted on the ground, the base fertilizer is mainly decomposed farm manure. In summer, there is much rain, and the fertilizer applied should not be more or less. Generally, a depth of 15 cm is better. Otherwise, it will cause infiltration and loss of fertilizer. The depth of fertilization is very helpful for crops to absorb nutrients.
2. Summer fertilization keeps multiple thin application
Summer temperatures are high, there is a lot of rain, and crops grow fast. These characteristics require that we use split fertilization when fertilizing. This can avoid nutrient waste and soil problems caused by a large amount of fertilization, improve fertilizer utilization, and excessive fertilization will cause soil pollution, lead to increased soil fixation, change the physical and chemical properties of the soil, and affect the normal growth of crops.
3. Fertilization should be reasonable
Summer mature crops have a relatively short growth period, and it is necessary to grasp the characteristics of the crop's fertilizer requirements and choose the appropriate fertilizer for application. In actual production, organic fertilizers can be combined with chemical fertilizers, controlled-release fertilizers with quick-release fertilizers, and rhizosphere fertilization with foliar fertilization. The mutual coordination between them and the joint use of fertilization methods can meet the growth needs of crops.
2. Anti-freezing damage of summer mature crops
1. Strengthen fertilizer and water management, clean up ditches in a timely manner, ensure smooth drainage, adjust field humidity, and then do a good job of cultivating and loosening soil.
2. Reasonable application of chemical fertilizers
For crops suffering frost damage, potassium dihydrogen phosphate can be applied, and organic water-soluble fertilizers can be sprayed to promote photosynthesis, which can resist low-temperature frost damage and allow crops to grow faster.
3. Increase the application of organic fertilizer
Straw mulch is used to spread grass and plant ash or chaff and other measures to keep the seedlings warm, and high-temperature composting of livestock and poultry manure and compost of straw rot are added to improve soil gas and heat conditions.
The above is a complete introduction to fertilization and freezing damage prevention methods for summer mature crops. If farmer friends want to grow high-yield crops, they must master scientific fertilization and freeze damage prevention methods. I hope the above content will be helpful to everyone.
