And the other is the technique for planting clover in peach orchard for preventing weed.
Clovers can be interplanted in spring or autumn in the orchard, and the sowing and the propagation can be carried out. Spring is in the last ten days of March from 2 months, autumn is in the middle ten days of 10 months to 11 months. After sowing, it is necessary to ensure that the surface soil is wet or covered with a covering for shading. The sowing amount of the clovers is preferably 3-5 g/square meter, the seeds and the fine river sand are uniformly mixed during sowing, the sowing is manually carried out, the sowing depth is 1-1.5 cm, and after the seeds are sowed, the seeds can be raked into the soil by a rake or covered by 1 cm of the soil.
1. Seedling stage management: the clover grows slowly in the seedling stage, after seeds are sowed, spraying and watering are carried out every morning or evening, the soil surface is kept wet all the time until seedlings emerge, the number of water spraying times can be reduced after the seedlings emerge, the watering is carried out once a week, the management still needs to be meticulous, and the seedling stage management lasts for about 30-50 days.
2. Orchard management after seedling emergence: the clover basically does not need to be intertillage and weed after being interplanted in the orchard because of strong encroachment performance. No nitrogen fertilizer is applied in production, but the dosage of the fertilizer is 10 percent more than that of the conventional phosphorus potassium fertilizer when clovers are not interplanted. Can be cut once before summer and irrigate with enough water. And (5) mowing once again before overwintering, and watering the winter water fully. Thus, when turning green in the next year, the lawn has no withered and yellow branches and leaves.
Comparative example 1.1: the clover in example 1 was replaced with ryegrass, and the rest was identical to example 1.
The ryegrass is tall and vigorous, and is generally mown for at least 4 times in 3 to 6 months, the clover is short, and the ryegrass is not vigorous in growth, and can be mown only once before the summer, so that the labor is greatly saved.
The invention is mainly based on peach orchard, but pear orchard can also be suitable. The diseases and insect pests of peach trees and pear trees are similar, bagging cultivation is needed in production, fruit trees such as oranges and tangerines are different from peaches and pears in disease and insect pests, and bagging is not needed in production.
Finally, it is also noted that the above-mentioned lists merely illustrate a few specific embodiments of the invention. It is obvious that the invention is not limited to the above embodiments, but that many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the invention.
