1, the application time should be timely, whether as a base fertilizer or top dressing, should be applied at the right time. The application of base fertilizer is too early, and the fertilizer has lost its effect when the growth of the seedlings has not yet played a role. If it is applied too late, it will continue to exert its effect on the growth of the seedlings in the late stage, causing the length of the seedlings, delaying the sitting and reducing the rate of sitting. The correct application should be applied to the cavity about 10 days before the planting.
2. It is necessary to crush and ferment the cake fertilizer to form a hard block during the pressing process, which needs to be pulverized into small particles to be evenly applied and decomposed by soil microorganisms as soon as possible. The cake fertilizer can generate a large amount of heat during the decomposition process. When it is applied as a top dressing, it must be decomposed by fermentation and then applied to avoid "burning roots".
3, the amount of appropriate cake fertilizer is a kind of organic fertilizer with high economic value, in order to be as economic and reasonable as possible, the dosage must be appropriate. The use of cake fertilizer as the base fertilizer, the general amount of mu does not exceed 40-50 kg, the amount of topdressing generally does not exceed 60-75 kg. If the plant is applied, 100-150 grams per plant is applied.
4, the depth of application should be suitable for the application of cake fertilizer should be slightly deeper than chemical fertilizer, the base fertilizer is about 25 cm, and the topdressing is about 15 cm. When topdressing, do not be too close to the root, so as not to cause "burning roots"; nor too far from the roots, so as not to absorb the roots. Generally, the vine is about 25 cm away from the root, and the expanded melon is about 30 cm from the root. Watering was continued 2-3 days after application.
5, mixed with scientific cake fertilizer is less, can be mixed with other organic fertilizers. But try not to mix with fertilizers, so as not to cause plants to grow or cause root burning.
