Embodiment 1

[0027] Example 1, adopt the following steps to prepare sweet potato residue: wash the sweet potato and put it into a sweet potato grinder to break it into small particles with a diameter less than or equal to 1 mm, then add water 3 times the weight of the sweet potato, and put it in a sieve with a 100-mesh screen Rinse and filter. Sieve out the slag larger than 100 mesh, and the mixture of sweet potato fine slag, sweet potato starch and sweet potato juice less than 100 mesh leaks out of the sieve and flows into the starch separation tank. In the separation tank, the starch is separated from the mixed liquid with physalis for making vermicelli. After 20 minutes, 99% of the starch will settle at the bottom of the pool. Before extracting the starch, the mixture of sweet potato residue and sweet potato juice must be skimmed off, and the mixture of sweet potato juice residue on the upper end of the starch must be pumped out with a catheter with a diameter of 20 cm. After 24 hours ...

Embodiment 2

[0043]Embodiment 2, this implementation case provides the cabbage field fertilization method, adopts the sweet potato residue that embodiment 1 makes: before sowing cabbage, the vegetable field is opened a trip deep about 10 centimeters shallow ditch, in the ditch every rice spreads Add 1.5 to 2 kg of sweet potato residue, then bury the top soil, and build a small soil ridge about three centimeters high, so that there will be more rain in early autumn and the cabbage will prevent waterlogging. Sow seeds on small ridges. This method is safe and effective. It will not burn the roots by the sweet potato residue fertilizer, but also ensure that as the cabbage roots grow stronger, the fertility will be continuously input. During the growth of cabbage, it was found that the cabbage leaves were immune to aphids due to the application of sweet potato residues, and there was no aphids, which proved that sweet potato residues had a repellent effect on aphids.

Embodiment 3

[0044] Embodiment 3, this implementation case provides the method of fertilizing the scallions: every July, before planting the scallions, the sweet potato residue is evenly sprinkled on the surface at an amount of 2 kg per square meter, and then deeply plowed into the soil. Dig the ground to support the ridge, plant the green onion seedlings in the ditch, bury about 3 cm of soil and then water. In order to ensure the height of scallions and their ability to grow upright, the ridges should be continuously supported during the production of scallions. Every time the ridge needs to be watered to satisfy the growth of green onions, because the sweet potato dregs can kill onion flies, ground maggots, etc., ensuring a 100% survival rate of the green onions, and it has the effect of fumigating and killing the pest thrips on the leaves of the green onions. The surface of the scallion leaves is smooth and green, and it tastes very good and very delicious.

Abstract

The invention belongs to the field of planting fruits and vegetables and relates to an application, as well as an application method of sweet potato residue for planting fruits and vegetables. The sweet potato residue can supply various microelements required in growth of plants and is in a solid form, so that slow-releasing and long-acting effects are achieved during application. The sweet potatoresidue is convenient to broadcast. A test proves that the sweet potato residue has killing or repelling effect on pests underground, and has significant killing or repelling effect on small foliar pests, such as aphids and thrips on earth surface. The sweet potato residue can be produced from natural substances, is environment-friendly, is beneficial and harmless to body health, solves a problemof residual pesticide and chemical fertilizers, has extensive raw material source, is low in cost and can be promoted and applied in a large range.

Description

technical field [0001] The invention belongs to the field of fruit and vegetable planting, and relates to the application and application method of sweet potato residue in fruit and vegetable planting. Background technique [0002] Leek is delicious and nutritious, and it is an indispensable dish on people's dining table. However, in the process of leek production and management, the problem of drug residues caused by the prevention and treatment of leek maggots has always troubled vegetable farmers. In recent years, incidents of leek poisoning, fruit and vegetable poisoning have repeatedly have happened. The reason is that in order to kill leek maggots in the roots of leeks or other fruit and vegetable pests, vegetable farmers use a large amount of highly toxic insecticides for irrigation and spraying, resulting in pesticide residues. In addition, there are still problems such as chemical fertilizer pollution and residues in the process of fruit and vegetable production. ...
