Description

Technical Field

[0001] The invention belongs to the technical field of agricultural production, and in particular relates to a seedling-raising nutrient block. Background Art

[0002] The current method of raising seedlings is to place a plug tray on a siphon tray, and sow seeds in each groove of the plug tray through a sandy soil matrix to raise seedlings. During the production process, nutrient solution needs to be added regularly for production, which is labor-intensive and time-consuming. When farmers relocate and transplant seedlings, the roots of the seedlings are prone to loose soil, which may affect the growth progress at best and cause death of the seedlings at worst. Summary of the invention

[0003] The technical problem to be solved by the invention is to provide a seedling nutrient block which is easy to produce and manage.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A seedling nutrient block comprises worm sand, sticky organic matter and crop fermentation material raw materials, the ratio of the worm sand to the crop fermentation material mixture is 4:6, and the ratio of the mixture to the sticky organic matter is 1000:0.5-1.5.

[0006] Preferably, the insect litter is grub insect litter.

[0007] Preferably, the sticky organic matter is powdered crops.

[0008] Preferably, the viscous organic matter is cassava flour, sweet potato flour or potato flour.

[0009] Preferably, the crop fermentation material is straw fermentation material.

[0010] Preferably, the grub litter is made of 2-3 month old larvae, and the breeding site of the grubs includes building a microfiber board cement breeding pool or indoor three-dimensional production or outdoor large-scale production.

[0011] Preferably, the microfiberboard cement breeding pond is constructed in a rectangular shape with a depth of 60 cm; when the grubs are cultured indoors in a three-dimensional manner, the thickness of the added feed is 6 to 10 cm, and the breeding can be carried out at a stocking density of 3.0 kg / ㎡. The number of breeding layers can reach 6 to 8 layers, and the height between layers is 80 to 100 cm; when the worm sand is produced on a large scale outdoors, the topsoil is excavated to a depth of 15 to 30 cm, and the food stacking height should reach more than 50 cm.

[0012] Preferably, the raw material of the grub feed is crop straw or vegetable vines or fallen leaves or weeds or lawn clippings or edible mushroom chaff waste or livestock and poultry excrement or wet garbage or various organic wastes, either alone or in combination.

[0013] Preferably, the raw materials are collected and crushed, and then the humidity is adjusted to 55%. Then, 2% of the weight of the material urea and 0.1% of the weight of the material decomposing bacteria and water are mixed and stirred evenly, and then sprayed evenly layer by layer on the feed. After completion, a pile with a width of 1.2-1.5m, a height of 0.8-1.2m and unlimited length is built for fermentation. After the pile is built, it is covered with plastic film for heat preservation, or directly built in a sun shed for fermentation. Aerobic composting is carried out at 25°C for 15-25 days to obtain fermented feed that can be used to feed white-spotted flower beetles.

[0014] The beneficial effects of the present invention are as follows: since the nutrient blocks of the present invention contain sticky organic matter, the nutrient blocks are not easy to disperse, and thus traditional plug trays are not needed. By not using plug trays, costs can be reduced, survival is basically not affected during cuttings, and there is almost no growth buffer period. Insect sand and straw fermentation materials are used to make nutrient blocks for seedling cultivation, which themselves contain relatively high nutrients, and thus no nutrient solution needs to be added during the production process, thereby further reducing management costs, saving labor and time, and solving the environmental pollution problem caused by straw burning. Since the nutrient blocks of the present invention contain crop fermentation materials, the nutrient blocks have better water absorption. By directly placing the nutrient blocks in the siphon tray of the present invention, the nutrient blocks can directly absorb water from the siphon tray, and watering is more uniform than the traditional spraying method, and there is no problem of inadequate watering. Moreover, the present invention does not require manual watering, and only water needs to be poured into the siphon tray. DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the embodiments.

[0016] This embodiment is a nutrient block for seedling cultivation, which is composed of: grub sand, cassava flour, and straw fermented material. Ratio: The ratio of grub sand to straw fermented material is 4:6, and water is added to adjust the humidity to 50%. Cassava flour is 300 mesh fine powder, used as an adhesive, and 1 kg of cassava flour is added to one ton of nutrient block mixture, and it should be mixed evenly before use.

[0017] The production of nutrient blocks uses the paper pot seedling automation system provided by Dongguan Enzhuo Intelligent Technology Co., Ltd. The paper pot seedling automation system: automatic tray arrangement, automatic sowing, automatic soil covering, automatic watering, and all nutrients are decomposable, meeting the environmental protection requirements of large-scale seedling enterprises.

[0018] In this embodiment, the grub litter is the litter of 2-3 month old larvae, which comes from Yuanjian Agricultural Group Co., Ltd. and mainly provides nutrients for vegetable seed seedlings, such as: Solanaceae, melon, and cruciferous seeds.

[0019] The sources of grub sand include three breeding methods:

[0020] ①Build a microfiber board cement aquaculture pond. The specifications can be adjusted according to the actual site conditions, basically maintaining a rectangular shape and a depth of 60cm. The reason for using microfiber board to build the aquaculture pond is to avoid legal issues related to land (hardening of the ground is not allowed).

[0021] ②Indoor three-dimensional production of larvae. The larval stage is the main period for processing and transforming decomposed feed. The larvae lurk in the lower layer of the feed pile and like to live in groups. Therefore, they can be cultured indoors in a three-dimensional manner. When cultured indoors, the thickness of the added feed is generally 6 to 10 cm, and the culture can be carried out at a stocking density of 3.0 kg / ㎡. Indoor culture of white star flower beetles mainly uses assembled shelves, plastic basins and other equipment.

[0022] With the development of intelligence and facilities, larvae can also be fully automated indoor three-dimensional culture, by controlling the indoor temperature, light, humidity, ventilation, feeding and other automation, to achieve full automation of larval culture. Generally, the number of layers of culture can reach 6-8, and the height between layers is 80-100cm.

[0023] ③Large-scale outdoor production of larvae. When breeding white-star flower beetle larvae outdoors, the topsoil should be dug to a depth of 15 to 30 cm, and the height of the feed and other food materials should reach more than 50 cm. If conditions permit, a cement pool can be cast to effectively prevent the larvae from escaping. In northern regions, white-star flower beetle larvae can be produced outdoors on a large scale. In southern my country, due to the heavy rains from April to October, large-scale outdoor breeding requires the construction of greenhouse facilities to shelter from the rain. The greenhouse facilities constructed should be equipped with sunshade nets to prevent damage caused by excessive sunlight in the summer. At the same time, attention should be paid to ventilation to prevent excessive temperatures. Water curtains and fans can be installed.

[0024] The production machinery mainly includes straw and other material crushers, material mixers, material compost turners, insect body and insect sand separators, microwave dryers, etc. The small tools mainly include: transport carts, feeding utensils (basins, boxes), egg-laying sieves (the egg-laying sieve includes an outer plastic box and a matrix egg sieve. The outer plastic box measures 38cm×50cm×14cm, and the matrix egg sieve measures 38cm×50cm×13.5cm. The side aperture is 0.8cm×0.8cm, and the bottom aperture is 1.0cm×0.8cm), large and small insect and insect sand separation sieves (4, 6, 8, 10, 12, 16 mesh), etc.

[0025] Preparation of grub feed:

[0026] First, the raw materials are selected, then crushed, and then composted. The raw materials include corn stalks, wheat stalks and other crop straws; vegetable vines; fallen leaves, weeds and lawn trimmings; edible mushroom chaff waste; cow dung, pig dung, chicken dung and other livestock and poultry excrement; wet garbage and other types of organic waste.

[0027] Composting treatment: Before composting, adjust the humidity of the raw materials to 55 for standby use. Then, mix and stir 2% of the weight of the material with urea and 0.1% of the weight of the material with decomposing bacteria and water, and spray them evenly layer by layer on the feed. After the inoculation is completed, build a pile with a width of 1.2-1.5m, a height of 0.8-1.2m, and an unlimited length for fermentation. After the pile is built, cover it with plastic film for insulation, or build a pile for fermentation directly in the sun shed. Aerobic composting at 25℃ for 15-25d will obtain fermented feed that can be used to feed white star flower beetles. In short, composting pretreatment is very important, and the material must be fine and the fermentation must be uniform, so that the white flower beetles can eat quickly and grow well. It is best to use the composted materials directly. If they cannot be used in time, they should be dried and stored for standby use to prevent the breeding of other saprophagous insects and miscellaneous bacteria. On the other hand, you can take advantage of the warm conditions in summer to compost a large amount of materials in the appropriate season. After the composting is completed, dry them for wintering and expansion, which can reduce production costs.
