The key points of asparagus planting technology, fertilization should also pay attention to the time period!

Asparagus is a common food in our home-cooked dishes, as one of the plants of the asparagus family, it has many aspects of nutrition. Asparagus can also be called asparagus, asparagus, generally we eat the finished products are green state, often with bacon, fresh meat and other foods. So do you know the planting technique of asparagus?

Planting techniques of asparagus

Farmers may be both unfamiliar and familiar with asparagus, and if it is a novice planting for the first time, they will inevitably be confused. The editor has summarized the planting techniques of asparagus for everyone. Let's take a look:

1. Soil

Before planting green plants, we need to observe whether the soil is suitable or not. Asparagus is usually cultivated in sandy loam. Sandy loam soil is relatively loose, and the drainage performance is good, and the permeability is strong. It can not only play a good role of protection in the process of asparagus growth, but also can be absorbed by nutritious water sources. Asparagus can accept slight salinity, we should pay attention to when the salinity test, more than 0.2% asparagus will die.

2. Temperature

Asparagus is easier to feed than other plants that prefer warm or cold environments. Asparagus is very adaptable, no matter it is cold or hot. When the temperature is higher than 30 degrees, it will slightly affect its germination rate, so you can choose to sow in spring to avoid the high temperature. When the temperature is low in winter, the exposed parts of the soil may wither, and the fleshy roots in the soil enter a dormant period and grow safely after overwintering.

3. Moisture

The root system of asparagus is well developed and has a good bearing capacity for dry land. Generally speaking, more watering is needed during the critical period of bamboo shoot picking, and most of them are in the dry season, and the reduction in production will cause retraction to the tender stems of asparagus and affect the subsequent growth. If it coincides with the arrival of the rainy season, we should also pay attention to the drainage performance test of the soil to avoid root rot.

4. Sowing seeds

Asparagus sowing needs to carry out specific requirements according to the state of seed germination and the whole temperature environment, and the environment of each region is different, so the specific operation will be a little different. According to the temperature, we can choose to sow seeds in weather above 10 degrees. Spring is the most appropriate in the north, and spring and autumn can be carried out in the south. When sowing, we need to control the quantity, and the subsequent growth if the amount of sowing is too much, it is easy to cause the plant to stretch and affect the development. Generally speaking, it is most appropriate to carry out according to the distance of 50 cm between rows.

5. Fertilization

Green plants can not be irrigated without fertilizer. Asparagus is generally divided into three stages: seedling, juvenile and adult. Asparagus in seedling stage usually uses plant ash, livestock manure and nutritious soil to replenish energy. Roosters and hens raised by farmers are also good fertilizers, and chicken manure can also be mixed with them. When it is young, asparagus can be irrigated with nitrogen, phosphorus and ternary compound fertilizer. Rotten fertilizer is conducive to growth, and attention should be paid to turning the soil to maintain its looseness. After adulthood, the fertilization of asparagus is generally controlled at about three times a year, and compound fertilizer or organic fertilizer can be added in spring, which is concentrated before harvest. In the later stage of harvest, more compound fertilizer is needed to increase nutrition. Autumn as the peak period of heading, in order to make asparagus grow faster, we can eat potash fertilizer, phosphate fertilizer and nitrogen fertilizer to irrigate.

This is the end of today's introduction to the planting technology of asparagus. Asparagus is a delicious hard dish, whether it is stir-fried or stewed soup or dry pot. But it is important to remember to eat less asparagus during allergies so as not to trigger deeper allergies.
