Notes on the cultivation of cauliflower and technical points of fertilization
The cauliflower belongs to the cruciferous plant cabbage, which is served by huge flower buds and is a very precious vegetable. Rich in nutrients, rich in protein, fat, carbohydrates, dietary fiber, vitamins and minerals. And often eat cauliflower has the effect of cooling throat, opening sound, moistening lungs, and relieving cough, so it is very popular among people. What are the precautions for planting cauliflower and the technical points of fertilization? Let's go check it out!
First, the fertilization type of cauliflower
As a shallow-rooted plant, cauliflower is both wet and scary. Generally, it requires loose soil for normal growth and good fertility. Therefore, in the production, high-quality organic fertilizer is used as the base fertilizer. Such as decomposed chicken manure, manure, biogas slurry, grass ash, etc., chemical fertilizers include urea, calcium, ammonium bicarbonate, diammonium phosphate, potassium sulfate and other compound fertilizers, trace element fertilizers, etc. (Accounting for more than half of the total fertilizer) In addition to the decomposed base fertilizer in the base fertilizer, appropriate amount of available nitrogen and phosphate fertilizers should be applied. The topdressing is generally carried out in the early stage of flower bulb formation, with quick-acting nitrogen fertilizer and potash fertilizer as the main, and professional growers. Introduction, in the mid-late maturing varieties cultivated in autumn, in addition to sufficient base fertilizer, there should be 2 to 3 times of topdressing, the amount of base fertilizer is more than that of early spring ripening, and the topdressing fertilizer is still mainly available nitrogen and potassium fertilizer.
Trace elements such as molybdenum and boron are generally applied with the base fertilizer. The advantage of applying farmyard manure is that it can reduce the probability of occurrence of trace element deficiency to a certain extent.
Second, the cauliflower fertilization period
To grow cauliflower, to obtain high yield and good quality flower balls, there must be strong leaf clusters to ensure. It is required to meet its demand for water and nutrients in a timely manner, so that the plants grow vigorously in a timely manner, so that they can form sufficient nutrient area in the number of leaves before the current ball. Therefore, under the premise of applying the base fertilizer, timely topdressing.
1. Early maturing spring cultivars: The organic fertilizer in the base fertilizer should be applied before ploughing, while the inorganic fertilizer is applied during the whole hoeing or planting. If the mulch film and the small arch shed are covered and cultivated, it is possible to apply the base fertilizer by ditching, cover the mulch after watering, and then plant the method. The mulch film is in contact with the ground, and the water retention and water retention are good. Top dressing is generally carried out at the beginning of flower ball formation. Due to the short development time of the flower bulb and the large amount of fertilizer required, it is necessary to use quick-acting nitrogen fertilizer and potassium fertilizer, or a compound fertilizer (such as potassium nitrate) and a compound fertilizer with a high proportion of nitrogen and potassium.
2. Mid-late ripe cultivars: Due to their long growing season, the amount of fertilizer needed is large. In addition to the need to double the application of base fertilizer, the amount and frequency of topdressing should be more than that of early-maturing varieties. The first top dressing was slow seedling fertilizer, which was carried out 7 to 10 days after planting, and the main effect was nitrogen fertilizer. The second time is the ball fertilizer, usually before the formation of the flower ball. This top dressing is the key to the ball, and it will directly affect the quality of the flower ball. It is mainly based on quick-acting nitrogen fertilizer and potash fertilizer. Because of the large amount of top dressing, it is best to use calcium to prevent the absorption of calcium in order to prevent the soil salt ion concentration from being too high. Quick-acting nitrogen-potassium compound fertilizer, when the basic fertilizer is insufficient, this time, the nitrogen, phosphorus and potassium three-element compound fertilizer can be applied.
In the middle and late stages of the formation of cauliflower balls, in order to prevent premature aging, increase yield and quality of flower balls, it is also possible to spray 1~2 times of three-element compound fertilizer on the foliage. Foliar fertilization has obvious effects on soils with poor fertilizer and poor fertility in the middle and late growth stages of cauliflower.
Third, the amount of fertilized cauliflower
Early-maturing varieties of cauliflower cultivated in spring, due to short growing season, 2500 kg of high-quality organic fertilizer, 20 kg of urea, 20 kg of superphosphate, and 50 kg of ash. If the effective molybdenum and effective boron-deficient soil are used, 50-100 grams of borax can be applied per acre, and 10-20 grams of ammonium molybdate can be dissolved in water and mixed with organic fertilizer or chemical fertilizer to be mixed as base fertilizer.
In the late-maturing variety or the autumn cultivation of cauliflower, the amount of base fertilizer is more than twice that of early-maturing cultivation. It is recommended that the amount of topdressing accounts for more than half of the total fertilizer, 15 kg of urea per acre, and 100 kg of plant ash. The application of trace elements is the same as that of early maturing.
Fourth, the fertilization method of cauliflower
The application method of the cauliflower base fertilizer is to firstly mix the organic fertilizer with the phosphate fertilizer and the medium and trace element fertilizer for a period of time, or the phosphate fertilizer, the medium and trace element fertilizer and the commercial organic fertilizer are fully mixed and evenly combined with the ground preparation and turned into the soil. Quick-acting inorganic fertilizers such as nitrogen and potassium fertilizers can be applied at the time of planting. The cauliflower top dressing is mainly based on quick-acting fertilizer. In the top dressing before the formation of the flower ball, it can be ditched and fertilized, or it can be used for digging and fertilizing the plant. After the application, cover the soil and water. After the formation of the flower ball, it is difficult to dit a hole, and the fertilizer can be applied or poured with water. Foliar fertilization can also be carried out, such as spraying 0.5% urea or 0.4% potassium dihydrogen phosphate.
In summary, if you want the yield and quality of cauliflower to a higher level, you need to pay attention to the precautions of cauliflower cultivation and the technical points of fertilization. I hope this article can help you.
