摘要:
Process for the production of cellulose paper pulps from vegetable masses, comprising the steps of mixing and conditioning a vegetable mass suitable to form a culture medium with an inoculum constituted of edible ligninolythic mushrooms, such as Lentinus edodes, Pleurotis Peryngii, Psajor-caju, and the like; extracting the so-obtained enzyme and adding it to the vegetable material for the production of paper pulp, mainly constituted of cultivated annual plants such as kenaf, hemp, flax, cotton and various stems and/or agricultural-industrial residues, such as cereal straws, maize stalks, and the like; conditioning and causing the mass to react; and lastly washing the mass after the biological attack, obtaining in this way a cellulose pulp to be submitted to possible mild final cooking and bleaching treatment. Apparatus for the realisation of the process, and cellulose pulps obtained by biodelignification of cultivated annual plants and/or agricultural-industrial residues.
摘要:
A method for planning crop rotations in at least one plot (h i , i=1...n) of land within a predetermined planning horizon or time (T), to implement a cropping method, includes the steps of: for said or each plot (h), determination of a set (C) of acceptable crops (c) based on the soil nature of the plot(s) (h), an availability of irrigation, exposure, and geographic coordinates; for said or each plot (h), definition of a succession of planting periods (t) until the planning horizon (T) is completed; specification of a plurality of desired crops (c i ) among the acceptable crops; choice of a σ sequence of k crops, where k≥2, among the desired crops (c i , i=1...k); definition of a plurality of eligible sequences σ of the desired crops c i to be assigned to plot h, according to respective predetermined time orders, subject to agronomic constraints including on each plot, uniqueness of the crop c to be assigned in each planting period t, and minimum and maximum area assigned to each crop c in each planting period t; determination, for each of the eligible sequences σ, and for all p sowing periods t of planning time T, of a total yield π h for said or each plot h, obtained as the sum of seasonal yields Y h in sowing periods t, in which each of the seasonal yields in a sowing period t is calculated based on a maximum number of crops k comprising the assigned crop in sowing period t, and the k-1 assigned crops, according to each of the sequences, in a corresponding k-1 number of consecutively preceding earlier sowing periods preceding said sowing period (Figure 1).
