Due to the high cropping index in China's vegetable fields, continuous cropping is applied throughout the year, fertilizer nutrient application is irrational, and the application of NPK fertilizer is large, the application of trace elements is low, resulting in unbalanced fertilizer supply, low utilization rate, and high-quality organic decomposition. With less fertilizer application, the soil in the activated plough layer is thin, and the root growth is hindered. Lack of symptoms due to lack of trace elements and induced diseases are exacerbated and crop resistance is poor. The following deterioration has gradually occurred in the soil environment of vegetable fields:
1. Soil compaction, reduced air permeability, reduced beneficial microorganisms, slow ripening of the soil, poor water retention, resulting in poor development of vegetable roots and poor resistance to high temperatures.
2. Soil acidification and salinization are aggravated, which inhibits root growth and makes root water absorption capacity of vegetable roots poor.
3. The accumulation of soil bacteria and hormones has increased, and the number of pests and diseases has increased. The damage to Vegetables has become increasingly serious, often causing root rot and even the whole plant to die. At the same time, the amount of pesticides was increased and the quality of vegetables was declining.
In response to the common problems in the above-mentioned vegetable production, the scientific research personnel of Xianyi Agriculture in Guangzhou passed many years of comprehensive management experiments on fertilization of vegetables in modern vegetable garden soils, and found out a scientific application technology for water-soluble fertilizers for vegetables, which can not only greatly improve Vegetable production, improving quality, especially increasing the output of vegetables under extreme conditions (high temperature, rainy, etc.), can also improve and restore soil and reduce the occurrence of pests and diseases.
First, the management of the seedbed
As the saying goes, good seedlings are good for half a year, which shows the importance of good seedlings in agricultural production. Suggestions: 1. Diluted 500 times with loyal organic fertilization and diluted 500 times with loyal inorganic high-nitrogen (30-8-14+TE) water-soluble fertilizer after emergence. Poured one or two times; 2. Diluted with foliar leaf with 750 leaves. Times + harvest busy dilute 1500 times spray 1 or 2 times. To develop a seedling with a well-developed root system, thick stalks, and thick green leaves.
Second, fertilization of leafy vegetables
The goal is to suppress reproductive growth and promote the growth of the target vegetative organs leaves or stems. It is recommended that the root be diluted with loyal organic water-soluble fertilizer 500 times + loyal inorganic high-nitrogen (30-8-14+TE) water-soluble fertilizer diluted 500 times, and the leaf surface diluted with the first leaf 750 times + harvest busy dilution 1500 times spraying , Apply once every 10 days or so. The leaf vegetables produced in this way are of good quality, high yield, and early harvest.
Third, fertilization of Fruits and vegetables
1. Before flowering: From the time of planting to before flowering, it is necessary to promote the development of new roots for vegetative growth, so that the nutrients will grow stronger and not prosperous. Roots are recommended to be diluted 500 times with loyal organic water-soluble fertilizer + loyal balance type (20-20-20+TE) or high-nitrogen (30-8-14+TE) water-soluble fertilizer diluted 500 times 1 to 2 times, leaf surface The first leaf diluted 750 times + loyal plant dilution diluted 3000 times sprayed 1 or 2 times. When it is about to flower, it will be applied with loyalty phosphorus (10-52-10+TE) for 1 time. The leaves will be diluted 750 times with the fruit and + 1500 times with the loyalty.
2. After flowering: The roots use loyal organic water-soluble fertilizer 500 times + Loyalty high potassium (14-6-32+TE). The leaf surface is diluted 750 times with harvesting, and the fruit is diluted 750 times with spray. , After the use of flowers and more + loyal US friends cover spraying 2 to 3 times, spray 7 to 10 days 1 time. In this way, the yield of fruits and vegetables can be greatly increased, the sweet and tender vegetables can be tendered, and the harvest period can be extended, thus greatly increasing the income of vegetable farmers.
