Straw returning to the field is an increase in fertility and fertility measures. It eliminates the air pollution caused by straw burning and also increases fertilizer production. In order to make effective use of straw by a large number of farmers, our agricultural experts recommend:
One is to pay attention to the depth of straw overturning. After the corn stalks are crushed and thrown into the field, deep plowing shall be carried out more than 25 cm deep immediately after the corn stalks are crushed and scattered, and the straw shall be completely covered and the land shall be leveled with a rotary cultivator. The stalks scattered on the ground must not be exposed to the ground for a long time. After being exposed to the wind and sunshine, they will lose too much water and reduce the effect of field return.
The second is to pay attention to the amount of straw burying corn stalks when returned to the field should not be too much, generally 500-700 kg per mu is appropriate. Too much land volume will not only affect the speed of straw rot and decomposition, but also produce too many organic acids in the rot and decomposition process of straw, which will also damage the roots of the crop.
The third is to pay attention to fine powder, straw to return to the field when using straw crusher to use a large straw, so that the straw crushed length of about 5 cm, so as not to excessive long straw soil pressure is not true, affecting the crop emergence and growth.
The fourth is to pay attention to timely irrigation, corn straw should also be based on the soil moisture content, timely irrigation, to promote the speed of straw rot, to prevent the straw in the rot process and the struggle for wheat contradiction. Where fields are reserved for spring sowing in the second year, it is necessary to provide early irrigation when the soil moisture is insufficient according to the climate conditions, and to promote straw rot. The drylands must be well-guarded after the corn stalks are returned to the farm. It is best to bring smashing or repression after the deep-turning and preserve the moisture so as to facilitate the decomposition of straw.
The fifth is to pay attention to make up nourishment and nutrient supplements, in order to solve the contradiction between microorganisms and seedlings competing for nutrients. In order to decompose organic matter, microorganisms will inevitably compete with crop seedlings for available nutrients in the soil and affect the normal growth of seedlings. Therefore, sufficient nitrogen fertilizer should be applied to prevent yellow seedlings from being competed with seedlings by soil microorganisms to decompose the straw. Before tumbling, it is necessary to supplement 10 kg of urea or 25-30 kg of ammonium bicarbonate and 15-20 kg of superphosphate per acre before reversing pressure. The replantation plot should increase the application amount of fertilizer, promote the decay rate of straw, and prevent straw rot and decomposition. Wheat is a problem with fertilizer.
Sixthly, it is necessary to eliminate the return of sick straw to the field. Such straw should be destroyed or used after high-temperature heaping.
Fresh fruit refers to juicy and edible plant fruit with sweet and sour taste. Fruit is not only rich in vitamin nutrition, but also can promote digestion.
Fresh fruits include all fresh fruit products which are harvested from the orchard and straightly sent to the processing factories.
As soon as the products arrive the factories, the workers will have to clean the products up by revoming the extra covering bags and dirt then wash them up with clean water for few times until the fruits are clean enough to preserve.
After cleaning process, the workers will choose the products according to the size and type for different markets all over the world. And then put those products in net bags into various cartons and packages.
Later on the cartons will be sent to the cold stores to lower the temperature for keeping the freshness of the fruits in order to deliver all fresh products to the customers worldwide.
Our fresh fruits include many kinds, for example, fresh Fuji Apple, fresh Huaniu Apple, pear, kiwi, fresh lemon, winter jujube, fresh peach, cantaloupe, mango and so on.
The fresh fruits are full of vitamins, fibres and nutritions for our daily life. They are good for our health.
