Method for interplanting walnut and Crocus sativus

Abstract

The invention discloses a method for interplanting walnut and Crocus sativus. Walnut seedlings are planted at a density characterized by a line spacing of 5-6 m and a plant spacing of 4-5 m, the Crocus sativus is planted between rows of walnut trees, plot ridging is carried out at a plot width of 1.2-1.5 m, and the Crocus sativus is planted at a density characterized by a line spacing 15-20 cm anda nest spacing of 8-10 cm. The method effectively solves the biological competition between the interplanted plants, the walnut trees have the characteristics of light enjoying, fast growth, early formation and long economic life, early-fruiting walnuts generally have a trunk height of 0.8-1.2 m, late-fruiting walnuts generally have a trunk height of 1.5-2 m, the walnuts have developed roots, theCrocus sativus is a perennial herbal medicinal material, has a plant height of about 15 cm, and belongs to a fibrous root system shallow root plant, and the method effectively solves the competitioncontradiction of the interplanted plants in water, fertilizer and light.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a planting method for walnut interplanting. Background technique [0002] Walnut is a deep-rooted deciduous fruit tree with a long tree age, which is divided into four age periods: the growth period is from the seedling planting to the beginning of flowering and bearing fruit, the early-fruiting walnut variety is 5-6 years, and the late-fruiting walnut variety is 7- 10 years; the growth and fruiting period is the period from the beginning of fruiting to a large number of fruiting, generally 7-20 years; the full fruiting period is the period when the fruit yield gradually reaches its peak and continues to be stable, generally 8-20 years; the aging renewal period is the fruit Yield decreased obviously, the backbone branches began to die, and the period of new branches occurred in the rear, generally starting from 80-100 years. The walnut root system is developed, the...

Problems solved by technology

However, in the prior art, the processing method in the walnut planting process is inappropriate, resulting in the waste of a large area of ​​vacant land in the walnut plantation, making the output of the walnut planting early stage lower, and requiring a large amount of labor to loosen the soil, Management and planting costs such as weeding and pest control are relatively high

Therefore, there are corresponding technical researchers in the prior art to interplant walnuts with other crops, especially to select species of the shrub genus for interplanting, but in the interplanting process, due to the inappropriate species selected, it forms an interplant with walnuts. Biological competition makes the nutrient supply of walnuts difficult and affects the yield of walnuts
