The present application relates to the field of plant genetic breeding, and particularly relates to a kind of evaluation method of asparagus yield. Including the following steps: S1, obtaining young plant period asparagus;S2, measures i variety of young plant period asparagus following parameters: photosynthetic rate A, ribulose-1,5-bisphosphate carboxylase / oxygenase activity B, leaf dry weight per unit area C, acid invertase activity D and root crown ratio E;The measurement sample of the acid invertase activity D is the tender stem of young plant period asparagus at 10-30cm from top;S3, according to the formula, the evaluation value is calculated, and the evaluation value is used to evaluate the yield of asparagus. The evaluation value obtained by using the above measurement index and calculation formula, and the significance level obtained by SPSS software is used to evaluate the yield of asparagus. The yield potential of asparagus can be comprehensively evaluated from the genetic point of view in a short time. Using the evaluation method of the present application, high-yield asparagus varieties can be selected in a short time without tracking for many years.

This invention relates to a root-and-crown co-regulatory variable irrigation sunscald control system and method. The system includes a variable frequency water pump, main pipe, branch pipes, an integrated spray irrigation system, and a data acquisition and irrigation decision control system. The operating mode of the integrated spray irrigation system switches based on soil moisture data and crop information monitored by the system. The irrigation volume under different operating modes is calculated by the system based on monitored soil moisture data, meteorological data, and crop information. The advantages of this invention are: based on the soil-plant-atmosphere water transport continuum (SPAC) theory, it enables the formulation of differentiated irrigation strategies for roots and crowns according to soil and atmospheric water requirements, and combines this with the integrated spray irrigation system to switch between different irrigation functions, effectively improving sunscald control and providing technological support for the development of smart irrigation agriculture.

A root phenotyping system is disclosed comprising a cleansing subsystem configured to suspend a plant in a cleansing container (C1, Cn) such that at least a root system (22r) thereof is submerged in a washing solution (13u) while being located at least partially within a growing media (13e) and a crown thereof is located at least partially within a nursery pot (12p), separate and remove the growing media (13e) from the root system (22r) supported by the nursery pot (12p). An imaging subsystem (15i) is used to acquire imagery data of the root system (22 r) supported by the nursery pot (12 p) from one or more angles, elevations and / or distances. A processing subsystem is used to process and analyse the imagery data and determine one or more properties of the root system (22r).

The application belongs to the technical field of sugar beet planting, and provides an integrated planting method suitable for sugar beet in spring drought area. The planting method comprises simultaneous seedling regulation and layered water preservation. The seedling regulation comprises: (1) seed disinfection; (2) composite seed soaking; (3) length control and germination promotion; (4) strong bud thickening; and (5) seedling stage regulation. The layered water preservation comprises: (1) land preparation and ditching; (2) three-layer structure laying; and (3) micro-area irrigation. The planting method can realize thickening of embryo axis, optimization of root-shoot ratio and improvement of osmotic regulation ability through the cooperation of simultaneous seedling regulation and layered water preservation, precise formula and quantitative parameters. Meanwhile, the planting method can match the root distribution characteristics of sugar beet, construct a long-term stable water supply environment, and realize the synchronous improvement of seedling survival rate, water utilization rate, yield and sugar content through the cooperation of endogenous drought resistance and exogenous water preservation.

This invention discloses a chemical topping method for optimizing root-shoot coordination and photosynthetic efficiency in cotton. The method uses a paclobutrazol-zinc complex as the topping agent, applied precisely during the topping period, and is coupled with localized cultivation management measures in southern Xinjiang. By systematically monitoring indicators such as plant height, number of fruiting branches, photosynthetic parameters, root productivity, and biomass allocation, the method achieves dynamic regulation and effect evaluation of cotton growth. Through a synergistic mechanism of shoot control, root promotion, and light enhancement, this invention significantly improves the net photosynthetic rate, root boll-setting capacity, and boll load of cotton, optimizes the allocation of assimilates to reproductive organs, and simultaneously and significantly increases seed cotton and lint yield while stabilizing fiber quality. This provides a reliable technical solution for green, high-yield, and high-quality cotton cultivation in arid regions.
