The invention belongs to the technical field of cotton planting, and provides a forage type low-gossypol cotton planting and mowing method. According to the present invention, the results of the fieldexperiments in the cotton areas of the middle and south area of Hebei province determine that the optimal planting density is 8000 plants / mu, the mowing period is from the flowering and boll-formingstage to the boll opening stage, the mowing period is divided in five mowing, the mowing position is the top third leaf, more than 3000 kg of fresh low-gossypol cotton branches and leaves can be harvested per mu according to the planting method, and the branches, the leaves and the stems of the mowed low-gossypol cotton can be directly fed to cattle and sheep after being crushed; the invention further provides a supporting technical measure adopted in a forage type low-gossypol cotton planting process, wherein the supporting technical measure comprises: land preparation, base fertilizer treatment, variety selection, rogueing, special cultivation management and the like; and through the scientific and reasonable planting and mowing method, the problem of poor palatability in the applicationof the branches, the leaves and the stems of the low-gossypol cotton planted by using the prior art as the feed is solved, the utilization value of the low-gossypol cotton branch-leaf-stem is effectively improved, and the new cotton planting utilization mode mainly as the feed is created.

The invention relates to the technical field of the water-retention fertilizer-conservation cultivation for the drought-resistant forestation of the agriculture and forestry, and concretely relates to a bentonite and fungal dreg compounded water-retention fertilizer-conservation cultivation matrix and its preparation method. The matrix comprises 30-40 parts of bentonite, 60-70 parts of fungal dreg and 0.1-0.5 parts of a composite fertilizer. The preparation method of the matrix comprises the following steps: selecting new waste fungal bags after the edible fungus plantation, carrying out bag removal treatment, crushing, and adding a composite microbial agent and urea to guarantee the C:N ratio of 20; fully and uniformly mixing the above raw materials, adjusting the water content to 60%, composting the fungal dreg, and storing the obtained compost in a ventilation and rain exposing prevention device for the decrease of the water content to 20%; and uniformly mixing the fungal dreg with bentonite and the composite fertilizer, and crushing to prepare the water-retention fertilizer-conservation cultivation matrix. The matrix has the advantages of abundant sources and low costs of raw materials, wide distribution and low cost of a bentonite mineral resource, large output and easy obtaining of the waste fungal dreg, simple making method, and no pollution to the environment.

The invention discloses a planting method for interplanting pea before sowing of sunflower. The planting method mainly includes: when fertilizing and mulching a land block where sunflower is prepared to be planted in early spring, planting pea on line space films reserved for sunflower at planting time about 20th March; watering the pea for the first time in early May, and combining watering with fertilizing; planting sunflower in reserved lines at the time from the end of May to the beginning of June; harvesting pea at the beginning of July, wherein yield of pea per mu is about 200kg generally, and yield of sunflower is not reduced basically and can reach about 250kg. High-efficiency three-dimensional planting technology is developed according to the circumstance that a Hetao irrigation area is sufficient for one crop and insufficient for two crops, and has the advantages that light, heat and soil resources are utilized fully, one-season two-harvest is realized, ground surface exposure is reduced, and sand storm is prevented. The planting method has double effects of increasing yield and income and protecting ecological environment of farmland and is high in practicability and wide in application prospect.
