Embodiment Construction

[0021] A method for planting organic purple sweet potatoes with water and fertilizer integration, comprising the following specific steps:

[0022] (1) Cultivate strong seedlings

[0023] Choose a plot sheltered from the wind and facing the sun with fertile soil, build an arch shed to cover the shed film to increase the ground temperature, and then build a seedbed with a length of 3m, a width of 1m, and a height of 15cm, and spread a layer of decomposed organic manure on the bottom of the bed, 2400 kg per mu, spray Wet cover with 5cm thick fine soil, and then select potato pieces free of diseases and insects to arrange seeds at intervals of 3cm, and then cover each potato piece with 2cm thick garden soil, and pour the decomposed organic liquid fertilizer with 3 times the amount of water on the seed potatoes, covering Mulch;

[0024] (2) Timely transplanting

[0025] When the potato seedling emergence rate reaches 60%, remove the mulch film, keep the temperature at 25°C and h...

Abstract

The invention discloses a water and fertilizer integrated organic purple sweet potato planting method. Purple sweet potatoes are planted through the aspects of strong seedling growing, timely transplanting, soil preparation and furrowing, field management and the like. Drop irrigation bands are laid on ridges, water and nutrients are conveyed to crops moderately in good time, the water and fertilizer needs of the purple sweet potatoes in the growth period are ensured, the water and fertilization utilization rate is increased, and human input is greatly reduced. It is avoided that that the growth vigor of the purple sweet potatoes are uneven, and the size difference is large, timely supply of the nutrients is ensured, and the situation that due to overnutrition, the yield is low, and the productive rate is low is avoided; the planted purple sweet potatoes are high in quality and yield and good in taste and has fewer fibers, and the method is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for planting organic purple sweet potatoes integrated with water and fertilizer.
